OBX Headers?

[rogerzr1]

Anyone familiar with these?

I have never heard of them. Not sure how they would bolt up. Sometimes it can be a nightmare making them fit up.

They are about 1/3 of the price of existing header options.

He has some interesting negative feedback but also alot of positive feedback. I just hate to see you get them and have them not work out for you. You usually get what you pay for. However maybe this will be the first inexpensive set available which would be great for those owners who are looking for headers at a fair price.

Those headers are 304 stainless. Stainless Work header are 409.

409 is a titanium stabilized ferritic stainless steel which means that it is a steel alloy containing chromium. It contains less nickel and more carbon than 304 stainless steel. Ferritics are best suited for high temperature applications that require corrosion resistance and high strength. The principal use of 409 stainless steel is automotive exhaust systems and most catalytic converter shells are made of 409.

More workable and stable than 304, 409 will accept bending and heat cycling better than 304. It resists both atmospheric and exhaust gas corrosion. It is magnetic due to its higher carbon content. Through chemical reaction, it oxidizes to a slight brownish hue which aids in corrosion resistance. While it does not polish well, it offers the advantages of higher strength, lower cost and longer life due to its heat handling qualities.

Someone who has all the measurements should contact them and get lots of pictures and measurements. A member could pull the trigger on them and then if they work out good, someone could approach them about a "Group Buy" benefiting all the the membership.

I would do it but I am not in need of another set of headers. Also, I'm not that familiar with header measurements etc.
By eyeballing them though they look decent - just like SW Headers.

I know the SW headers had issues with the dipstick tube when they first came out.

The first test would be if you can get these guys to give you what you need, detailed photos, specs, return policy etc.

Which brother of the beast wants to spearhead this project??

[ZZZZZR1]

Saw those too.... $450? WOW!


Doubtful they are an exact fit, I bet they copied another vendor?

Love more info on them!

[xlr8nflorida]

For comparison purposes:

[tomtom72]

JMHO:o If you do a comparison of the right side units side by side the cylinder #2 primary tubes look to be a different configuration....no?

Is it possible they somehow got a hold of the other header pattern? I seem to recall Watson and Jeal, or something like that? I would think there could be small differences between the two competing original header designs from way back when. I must admit I do not know enough about LT5 headers so I may be way off base here. Sorry.

Looked on their website. NA there.

I've heard of them from the LSx world. They just started making headers for the CTS-V, also at about half the price of the only other player. Several people said they've had them on other cars, and the fit and quality was good.

It sounds like they are made in Japan, though if anyone contacts them about them, I'd be interested to know if that's true/untrue.

If I didn't already have headers, I'd definitely consider them. $1000+ for headers is kinda crazy when you look at how cheap they are for so many other cars.

[ZZZZZR1]

Sent Marc Haibeck the link to the headers....

He said it looks suspect.

:cheers:

[Pete]

Heck,for that price i would not hasitate to try them.

[mgbrv8]

I just bought a set. I bought the full long tube exhaust from them for my 2003 Zo6 and it is a dead copy of the old design LG motorsports design except for the x-pipe instead of the h-pipe I had a 33hp and a 48ft/lb gain on the dyno and they sound awesome. The build quality was excellent and the fit was exact. I have had them on my car for 8000miles with no leaks or issues.

[pantera1683]

I really love my Stainless Works headers but if I was still in the market I would give these a try. The price point is more inline with headers for other cars and they look fairly well made. They may or may not be as good as the others but at least they are a low cost option.

Sorry but Frankie no likey :nono:

Maybe we should all buy inexpensive knockoff parts. And loose all of the suppliers that have been developing and researching parts for us. Be carefull.
My opinion, your opinion may vary.

I agree, I have SW headers. A set of headers for $1,200 is kinda crazy but I guess based on volume sales, we simply have to pay it.

Everybody likes a quality product for less $ but prefer if its made in the good ole USA. :usa:

[mgbrv8]

I payed $480 shipped but that was a while ago I think they went up to 6ish now sense the demand started going up.

Dave

[mgbrv8]

Ya I was going to make a set in the machine shop but when I saw this there just wasn't any way it was worth doing. Even then, any kit I would order from summit or jegs to make a set of headers would have been made overseas and I would have had to fab up some flanges. Oh and they arent mini cats they are just straight though with a little glass pack baffle, they are mainly ment to simulate cats they had the same set up on my ZO6 exhaust I ordered.

Also I just got a nice letter from the Warehouse in California with a notice that the Headers are shipped. Man that wasn't even three hours from the time of purchase, now thats service

Yeap,i agree.

What i would do is cut off those bullets/CATS and weld 3" pipes.
My Jeals cost me a total of $1700 w/shipping and coating.

You can buy these headers modify them and still have money left over to buy a nice exhaust system.

I think somebody should give them dimensions of an X-pipe wonder what they would charge for 3" x-pipe.

Competition is good.

We used 409 SS to make the Raptor turbo systems. I chose 409 for the stated properties, and agree that it does not polish well, but would go a step furter regarding the "slight brownish hue" to "pretty ugly brown" & hard to clean up.

I Jet coated my SS Works headers and recommend the process to others if you want to keep them nice looking.

[ammrpm]

Subscribing... I would like to know how these headers work out if anyone tries them!

Dam its about time. Cool!
Im am sure there will be a market for them with a good review.
Headers used to be $149.00 for v-8's.

Funny posts here, you guys remember how awful the 90-92 headers are from the factory, these ones look 10x's better already than anything GM put on the LT5.

$450.00 is a great price if they are a no drama installation.

Paying $6k+ for headers is just lunacy, but hey if you have money to burn why not.

Looking forward to hearing all about them.
I keep this in mind there has been issues about every brand out there, fitment, flanges, ect.
Get them coated!

Coated?? For heat purposes maybe? I was thinking about some header wrap. I'm not really worried about discoloration the ones on my zO6 still look pretty good.

Ceramic coating is the way id go, But wrap away! I have read the metal can split because of the overlap of material.
On my 92 the ceramic coated watsons (which were great BTW) really heated things up, I couldn't imagine uncoated.

They split if you don't wrap properly or overwrap properly I should say because the metal gets different temps etc.

I was looking to put headers on my 91 soon. I just got an email for the seller. Those are resonators, not cats. We have a road side drive by emissions test in Colorado. You think it would pass with out the cats? If we miss a drive by we need to do the std emission test. Those resonators would surly pass the visual test as a cat, but not sure if a sniffer would pick it up.

[Aurora40]

You could add cats, just like some people do with SW headers.

[Paul Workman]

Great price - 'bout the deal I got on the group buy that Dave arranged a year and some ago on the SW headers. (Thanks again, Dave!)

Smooth, gradual transistions mean a lot, when it comes to swaging pulses into tight places, and the closer to the source (engine), the more important it is for "impedance matching" (if I may borrow a term from electronics). Far as that goes, and without anything in the way of real data to go on (so take it for what it is worth), I like the SW's collector much better than the the pictured OBXs (or Watson headers too, for that matter!). So, like little "Mikey" in the cerial commercial...

"I'm not gonna try it...YOU try it!"

Well, I hope someone does try them and tells us what they think.

P.

[Aurora40]

Where did you see they are made in China? I couldn't find anything on their website about where they are made.
Did some more searching, and it does seem that they are made in China.

[todesengel]

I don't know about the domestic world, but in the import world obx is considered by many to be the junk of the junk. I would avoid them like the plague if you value good fitment, quality welds and longevity in a product. personally putting headers on the zr-1 is a project that I would only want to do once :-D

[Pete]

Here's a little something to ponder on.

SW has install/fitment issues also.
So if i had a choice i would rather get screwed for $400 then $1300.
I'm a cheap screw.:)

Those who have SW headers on there Z's go look under your Z one header hangs lower 1"-2" ,this was mentioned to them.

Jeals are the best i have seen & worked with,of course they were made in Germany,those Germans can build some sh!t.

Do a search on LT5 SW headers.

I'm not a hater what i do hate is a monopoly on LT5 parts.
As you all know monopoly is against the law in the USA.:fahne:

Pete

[todesengel]

While I appreciate competitive products as much as the next guy, you are assuming there is infact a product worth comparing.Go to supraforums, and look up obx headers, and read the posts. Not only are their headers made from far inferior materials, the workmanship seems to be non -existent, and welds are along the lines of a third graders abilities. Headers made by obx routinely rust out, crack, and require much work to make them seal properly, as well as much effort to reinforce, as well as brace..

Sometimes paying more for a quality piece upfront is infact being frugal, but I guess it is all a mater of how valuable your time is worth to you when you basically have to refabricate a part.Here's a little something to ponder on.

[todesengel]

It seems much of the older obx header crap on sf has been archived, or deleted. I could only find this one
Did you install this OBX header yet? Did it go OK??
I attempted to do mine yesterday and had a LOT of trouble. First the front part of the flange had to be ground A LOT to clear the head just under the distributor.Then the downpipe angle was ALL WRONG! (couldnt even attach it without hitting the transmission crossmember) and it therefore needed a bunch of additional bending (we had no choice but to just do heated bends) THEN after extending the O2 sensor wire 4' so it would reach we found the O2 sensor hole in the header was WAY TOO SMALL for the sensor! So we drilled it out about 3/16" larger so the sensor would at least fit in BUT THEN found the O2 flange mounting bolt/stud holes were not the correct spacing. THEN while using a die grinder to oblong the holes so we could mount the sensor, the flange broke completely off! - no doubt due to the fact that we had made the wall TOO THIN after drilling it to accept the sensor.
We ended up having to weld up the OBX sensor flange (what was left of it) and added a thread-in bung further upstream into the collector (the threaded style was all they had at the muffler shop) and used a GM thread-in 1-wire sensor. (not all that bad anyways as it will now work with the LSU4 WBO2 too)
But because the downpipe alignment was all screwed up , our test pipe and catback exhaust was now all out-of-whack and we had to bend it a bit and cut and reweld a couple of the hangers to make it fit.

All in all the WORST "bolt-on" header installation I have ever experienced.

Did Stainless Works change to 409? Mine are 3 years old and 304.

[xlr8nflorida]

Maybe I screwed up and its 304 - SW site says 304. Maybe earlier ones were 409 or maybe they have always been 304.
I'll have to stick a magnet on them and see if it sticks, that will tell me.

[mgbrv8]

Okay the headers are in I am going to start measuring and posting the info but I am going to put some pictures up first. They look really good the welds look great and there are no signs of pinholes. All the bolts holes on the flanges match perfectly.

Here are some more.

[EvanZR1]

Must say, those look pretty darn good for the price.

[Kb7tif]

[GOLDCYLON]

In response to the OP in post number one. My son is running these on his LS1 Camaro for about 2 years now, No fitment issues and they work well. They were an EBAY buy and They work well for the price IMHO. I for one am glad to see other "options" for our 20 year cars. Geesh guys you complain when nothing is avialable at a high price and then when presented with a possible low cost alternative that doesnt cost a fortune you still complain. I just dont get it? :icon_scra

[todesengel]

I don't see anyone complaining bout anything, where did that come from?

If someone has a different opinion now is that considered a complaint? I don't personally complain about the price of anything. The price of consumables is set by what the market is willing to pay.

The fact may be that the overall quality of these parts may be getting better, but it is still a crap shoot when you order. Much like buying a starter, or alternator at ghettozone, while it may have a lifetime warranty, how many times you want to climb under the car and replace it until you get a decent one?

Opinions are just that, and will vary from person to person, based on personal bias and economic situations.

I for one am under the belief that you buy the best product you can afford, and roll with your decision. I also believe that if you have to operate on a shoestring budget where $1200.00 is too much for a set of headers for your super car, then you may have purchased too much car for your wallet, or you don't modify it. These cars are getting old, and cost more to maintain than a run of the mill vette, so if you have to count every dime you have it may not be a good fit for you, imho.

Flame away, call me an ***, but I am a realist. I certainly hope that whoever purchases these obx headers for the zr-1 gets a great product, has zero quality, and/or installment issues.

[GOLDCYLON]

I concur with Polo-1's Whine post/ my complain post/ whatever label you want to put on it. Im running Jeal coated headers And dont regret the decsion. All im saying here is an alternative for those who dont want to pay $1200. I hope they work out for them. My son's pair work and look great. Your mileage may vary and glad to hear another vendor is supporting the LT5

We will just have to agree to disagree.

When I ran a shop I was constantly called by people who could barely speak english, trying to get me to send parts we fabricated to China, or what turned out to be, an importer in L.A. who dealt specifically with automobile parts imported from China.

It is disgusting to me that a person, or company can put countless hours into creating a new product, then have profits stripped from them for their work because someone sends their product to be "knocked off". Every product that company sells is knocked off of someone's hard work while they undercut the market with their cheap crap.

This is not a rant directed at you just a rant in general. I hardly doubt that anyone on this forum would appreciate the same done to them.

market competition is one thing, "knock-off's" are something entirely different.

Concur we agree to disagree. You are making bold assumptions as to what was "done" How is this different than the current knockoffs of the Jeal header molds being used that were orginally made in England? Opinions are like Axles, everyone has one. GC

You're right, I do assume these have been knocked off from an existing set, but I have past personal experience that makes me believe so. I have yet to see anything for the USDM market that came from China, that is NOT knocked off of an existing, or previously made item.


I didn't defend any knockoff.

Your reference to axles is just what my original point was before this all expanded. I am as entitled to my opinion as much as the next guy, especially when someone asks for an opinion.

Well Ok then. :hello:

This is great! You come on here swinging your bat, trying to diminish other peoples opinions because they do not conform to your own, then you want to turn the tables to make it appear I am trying to convince you?

You implied I was somehow defending one knockoff over another by bringing jeal copies into the conversation. I only spoke about the china crapola.

I have more than my opinion, I have been directly contacted by representatives of companies inquiring about parts to be knocked off. Apparently you missed that part of my post.

I knock a vendor based on the fact that their track history is junk. Personal firsthand experience rewelding, and reinforcing customers cracked manifolds for them. I have also had the pleasure of sending turbos off to be rebuilt after slag broke loose from inside of these same manifold, and wrecked their turbochargers.

The very fact that in their fleabay hawkings they put hks in the title of the knockoff they are selling because, with exception to quality, it is an exact duplicate of their item.

If you, your son, or anyone else wants to put a part like that on your car, go for it. I wish you all the best of luck.

Once again, here you are in the thread trying to demean other people as whiners, complainers, or whatever you want to call it. Funny how discussions always resort to some type of personal attack or another.

I guarantee you I have more first hand experience with their products than you ever have. representatives from their companies, and their importers. installation of their parts, and reinforcing them.

if you want pictures of theirs, what I had to do to support/fix them, or my own fabricated parts I am sure I can dig some up from my external drive and post them.

We disagree move on as for the bat comment you are way off center


You implied I was somehow defending one knockoff over another by bringing jeal copies into the conversation. I only spoke about the china crapola.

I never said you defended anything and your opinion is I implied I did. I ask how does one knockoff as you call it differ from the other? Other than anything made from China is crap. Got it. move on


I have more than my opinion, I have been directly contacted by representatives of companies inquiring about parts to be knocked off. Apparently you missed that part of my post.

I read it got it. Almost like my cousins sisters brother told me something once. Great got it.

Valid information however is this based on your opnion with OBX headers for the LT5? Well I doubt it because everything made in China is crap right? Got it

Thanks for reminding me I live in America and can do what I wish. Its amazing I spent 28 years in the Military and two combat tours in Iraq to defend "your" ability to too have an opnion and everybody else. How many times do I need to say I have your opinion on Chinese made products?


Once again, here you are in the thread trying to demean other people as whiners, complainers, or whatever you want to call it. Funny how discussions always resort to some type of personal attack or another.

Some people just complain to complain. Nuff said, How you feel this is personally demeaned you is unfounded. Its not about you. I was agreeing about a post of another forum member "polo-1" not you


I guarantee you I have more first hand experience with their products than you ever have. representatives from their companies, and their importers. installation of their parts, and reinforcing them.


Great who cares? I dont. Its all your opinion. I dont need your life history, It sounds like you have a wealth of exprience on imports. Great. Do you even own an LT5? Where do you think a lot of the replacement parts come from already especially aftermarket for the Corvette. From the global economy. Its great to see alternatives from other resources


if you want pictures of theirs, what I had to do to support/fix them, or my own fabricated parts I am sure I can dig some up from my external drive and post them.

No thanks. Your opinion is noted. Got it move on. Nobody is attacking you. My Original Post was to the Original Poster in post #1 as to my actual experience with OBX in which I had no issues. I also said some folks just complain to complain in agreement with Polo-1 and then you choose to chime in. Got it you hate Chinese products based upon your experience with inferior products. WE GOT IT. This is not about YOU or your opinion

[todesengel]

German trans, english designed engine, I think that would qualify a lot of people on the forums here with the same, don't you think?

Do you even own an LT5?
Nope, but I did stay at a holiday inn lastnight

I read it got it. Almost like my cousins sisters brother told me something once. Great got it.
Because the op asked for opinions, I was trying to share first hand accounts, and that experience is not pertinent somehow to his questions because it doesn't align with your thought process. Crystal

Valid information however is this based on your opnion with OBX headers for the LT5? Well I doubt it because everything made in China is crap right? Got it

Not really, I hear they make really good copies of Russian weapons, American guidance systems, and Japanese driveline

See my above post... Do you work for Stainless Works by chance? Or another vendor that make headers?

you caught me. I earn my living making headers for a niche car that was made in limited numbers. If I can only sell a set to the last 200 or so owners who do not have them on their car yet I can finally retire.

I'll buy you a beer for your service, but I hardly think you have a monopoly on this. Last I heard there was a couple hundred thousand of us who could pretty much say the same thing.

Some people just complain to complain. Nuff said, How you feel this is personally demeaned you is unfounded. Its not about you. I was agreeing about a post of another forum member "polo-1" not you

Labels, labels. People are content with putting others under one if they happen to disagree with their opinion on something.

Funny thing about forums is that replies are read by all, not just the op, or any other individual poster. When you throw generic labels out there, and lump anyone who disagrees with you into a group you are opening yourself up to a response.


As much as I would like to sit here all day and banter back and forth, I have to go to my hobby shop and start on another project. Maybe when this one is done I can sent some of my parts to the peoples republic of china and have them upgraded by peasant labor as well.

[Pete]

Easy there boys.

I think someone that experienced a product and had issues with it ,it's good to post up,nothing wrong with that.

Heck Jeal made killer headers but sh!tty cams,if the first guy came on here and posted there experience with Jeal cams, i wouldn't had to find out the hardway myself and a few others.
There are a few people still running Jeal cams and they would probably swear by them.

Remember Santa is watching,so be nice.:)

These OBX headers will never take the place of a new set of Stainless works and they shouldn't.
But looks like a halfway decent option to paying 1200+ headers. These would be great for getting some extra oomph from that just purchased daily driver. If I had just did a stoke job or engine upgrade another 1200 is nothing.

[mgbrv8]

As I stoop under the fire fight. I have a little off topic question, as I was removing my factory headers off the car I looked into the back side of each. I noticed that the drivers side headers catalytic converter was melted in the middle. Now would this be a sign of failing injectors, a failure of the smog system, a tune issue ( my car has a factory tune now but has had a tune on it in the past I believe), or a O2 sensor starting to degrade. It wasn't setting any codes before I tore it down and I had just finish a 10,700 mile road trip in it. Any constructive input would be greatly appriciate. Thank you gentalmen.

None of the above its possible that a piece of substrate broke off the honeycomb and melted into place. Impacts cause these to break apart before they ultimately fail. when they fail they start blowing chunks and the honeycomb tends to mold into a large ball of material. You will hear it as it sounds like a chock full of nuts under the car. This is a reason why a lot of us have gone to headers and Hi flow cats. Only other option is to find a NOS cat and exhaust manifold or hang a used one.

Ya it was a father a son road trip. I bought the car from Hammer and it was a impeccable example. We then drove it 10700 miles, 31 states and 55 museums over a seven and a half week period during the summer of 2009. Any where my father wanted to go I took him. It was a incredible jurney in a amazing car and every mile produce unforgettable memories.

Father and son trips are great. I drove my car from Houston in 2006 when I picked it up after my last tour in the box in Al Qayarrah. I had not seen my father for 16 months so it was a great ride back all the way back to Arizona except for the weather in Van Horn Texas (Heavy Snow). I ended up returning the ride along favor after my father bought his 96 CE from Tennesse. We had such a good time with the Z!

I apologize for my childish rants. Sometimes I just allow things to go too far rather than let them go.

If a mod wants to clean it up, that would be great.

Again, I hope anyone who spends their hard earned money on a set of these truly gets a quality product in return, I sincerely do.

Merry Christmas, and Happy new year to all of you.

I'm not disputing GC's statement as he actually went thru broken cats w/ his Z. But at BG this yr a brother had an ignition coil go out and you should have seen the glow at night....due to the unburnt gas from those cylinders...man they were a light show under the car. Just saying couldn't that circumstance provide temps beyond the melting point of the bricks?:icon_scra

I was watching one of those Car TV shows on the Speedvison last Sunday where the host was touring a Cat manufacturer. The rep w/ the manufacturer listed misfire dumping raw fuel, silicone contaminats and phosphate blow by (sounds familiar? All that discussion over ZDDP reduction in oil?) as being primary causes for cat failure.
Oh, yeah! It was a show called "Muscle Car".

Yes sir, that was me :o. Those cats were glowing red hot from only being driven a few miles with two cylinders out. I'll let you know how the top side of the cats look when I get them off next month for a header installation.

Hi, Tom,

Guess what? I have been reading this thread because my plan is to lose the cat and the factory exhaust manifold and slap on a set of headers. If you remember I have Florida tag and not encumbered by annual smog inspection.
In my opinion, just because it looks like a header and sounds like a header don't mean they all perform the same.
Although my knowledge is limited a successful header design should result in exhaust pulse stacking (at least equal length for all runners from the exhaust port to the collector), runner diameter (not too restrictive and yet not so large to stagnate the flow) and tunning effect (not quite figured out).
Bottom line, whether OBX is a knock off or not how good a knock off is it? The version they copied - how well was it designed?
Well, I gave up and sent an e-mail to Marc asking based on dyno numbers what is the best rwh he has seen between Jeal, Watson and SSW. Hopefully Marc can shed some light on the subject and I can make an intelligent decision.
Either way, exhaust headers and no cats!!!

[shaynezrl]

I just started reading this thread...i must say WOW!! OBX is making headers for our cars. I bought a set of their headers for my acura car years ago and it fit pretty good. There was a few thing that needed to be modified. The quality was not that good. At only $150.00 dollars it worked out good. Well you do pay for what you get. I only hope that they improve on their product since then. The headers that was posted earlier looked good and i hope the installation goes good.

Thanks to all the guys at BG this year for all of the great ideas on how to spend money on my car. Headers have been on the list for a while. I like the StainlessWorks units, but was pointed at the OBX at BG.

1) How did this install of the OBX work out?
2) It looks like the OBX collectors are slip fit with clamps, I've had problems with leaks trying to clamp SS pipes in the past.
3) Are the StainlessWorks headers fully welded or some assembly required too?

Trying to work through that $700 decision.

Had a great time at BG in 2012 and want to give special thanks to the FBI, Gordon Killibrew and Mark Haibeck for the fine hospitality for my son and I Friday night.

[efnfast]

I had a local shop do my OBX headers and exhaust. He charged me $750 for the install of headers and exhaust. I had him weld some of the non critical joints. I supplied him with Stage 8 bolts. He could not get the retaining clips on. I need to bitch at Stage 8 someday. So far I am pleased I went OBX and not S.W. Saved a ton of dough. I also had the headers ceramic coated by Swaintech. I went with their white lightning coating. It's not the prettiest, but retains a ton of heat, far more pretty coatings. It's all about performance baby. It was at BG, shame we didn't have a chance to hook up, you could have had a good look at it. -Steve

i would take a long look at the headers that corey henderson makes . i have a set on my 90 zr1 and a set of stainless works on my 92 the obx are exactly like them .the obx/stainless works made 17 less rwhp on my 92 . i found this out by switching the headers off my 90 to my 92 . coreys headers pipe lengths are between 22in to 24 in where the stainless works/ obx lengths are from 10 in to 22 in . i used the same dyno for both tests and allthough it was months between the 2 tests .i can feel the difference and at the drag strip gained 2.5 tenths and 1.7 mph by switching .coreys product is first cabin and isnt that much more than the obx considering that they come coated .jmho

[sammy]

by gained i mean 2.5 tenths less . just to clear that up

Hi Dave: Was hoping for the link to the Corey headers...

[CamP]

Hi Dave: Was hoping for the link to the Corey headers...

From what I recall, Corey bought the original Jeal headers jigs. Here's his contact info. http://www.hendersonperformance.com/hpt_contact.html

[Starman]

So niether the OBX or SSW are tuned (equal length tube)?

[zrss]

I ordered a set of headers from Corey in March of 2011 and am still waiting for them. In fairness to Corey I told him when I placed the order that I didn't need the headers right away so he probably didn't place a high priority on them. Now I'm ready and waiting.

[sammy]

just got an email from corey, and he shared he has just hired a full time fabricator and he will be working on building headers on Saturdays. if you need headers , if it were me i would wait for coreys headers . in my opinion they will be of excellent quality and are the only headers that are made for our cars that are worth the money . to me its just not worth it to buy headers that have lengths that go from 10 inches to 24 inches . i would put the obx headers into the shorty class. give him a call and decide for yourself. .

[sammy]

Do you have a link to these headers?i dont know how to do the link thingy .computer dummy . here is his email . corey@hendersonperformance.com

[sammy]

latest up date from corey, he should be turning out headers by the end of june .

[Kevin]

any idea on price

[zrss]

latest up date from corey, he should be turning out headers by the end of june . Excellent. Thanks for posting the information.

[sammy]

will try to get the low down on price whats included with the price of the headers .

[FU]

My 2 cent's FWIW, I'd wait for Corey's header's. But that's just me.

[zrss]

Corey quoted me a price when I placed my order. I don't know if he would be comfortable with me sharing that price so I won't, but it was better than the price for Stainless Works on their website. It only took a 5 minute phone call with Corey for me to get a price from him so anyone serious could just call him.

[sammy]

corey is working on finalizing everything and should post everything soon . till then if you want more details ,give him a call .you will find him to beone of the nicest,most honest people you have ever dealt with. as i stated earlier my car made alot more power with his headers than the stainless works/obx design and why not give our babies the best we can give them .jmho

[efnfast]

Ya know Sammy, I had a big note to self to buy headers from Corey. I got entised by price, probably gone pay the hp price. -Steve

[XfireZ51]

Brad,

What do you mean "lot more power"? Please give us something quantitative.
We know how reliable SOTP is.

[CamP]

Something to also consider is the OBX headers are made in China.

Corey's headers are made in Texas. :proud:

[Kevin]

metals still made in china probably

[mgbrv8]

Im still digging my OBXs I cant get over how they stay shiny most dull by now.

Dave

[sammy]

Brad,

What do you mean "lot more power"? Please give us something quantitative.
We know how reliable SOTP is.dominic , what i did was i dynod the car with the stainless works/ obx style then went and took off the headers of the 90 which has a blown head gasket ugh . and put them on the 92 and re dynod the car 2 day later on the same dyno and the car made 17 more rwhp and 6ft pound of tq more than with the stainless works set up . the only thing that was changed was the headers . what i found was the stainless works /obx headers primary pipes ranged from 10in to 24 in and the collector really pinched off where the primary pipes ended into the collector . in fact when i took the car to coreys a couple of years ago after putting headers on . the first pull on the car only netted a 3 wrhp difference 372 was stk and 375 was the first pull . corey did his magic and got it to 389rwhp now granted it was 2 different dynos. but it no where came close to the improvement i got from my 90 when i installed the jeal headers. that car went from 331 stk to 368 with just the header change . those tests where done on the same dyno but 1 month apart. the jeal headers primary pipe lengths were short 22in -24 in and the collector was a true collector not this pinched off thing. . also when i started taking the 92 to the strip the car trapped 112.6-113.2mph stk and after the install and coreys tune only went to 114.9-115.6 . i found extra power when i changed out the corsa which was on it stk to a 3in xpipe then went with the stk 23/4in pipe to 3 in super turbo mufflers with dual exits to keep a stk look . it now traps 117.5 118.6 depending on the da that day(that was still with the stainless headers ) . i have g teched the car with the jeals and it is up almost 2 miles ann hr over the gtech runs with the old setup . i hope to try to find some time this next month to validate my g tech numbers with real drag strip numbers . . to give a hint my 90 which only has coreys porting tune jeal headers and dr gas 21/2 exhaust trapped a high of 119.47 miles an hr . the da that day was almost 3000 ft . the 92 has the callaway porting in the inj housings and plenum and also has porting done on the heads .. pete was telling me that the callaway porting was not very good .soon as i get strip numbers i will post the videos and slips for everyone to ck out and decide for themselves which way they want to go .

[sammy]

oh just to clarify the 90 only has porting done to the inj housings and plenum . heads are still stk .

[ZZZZZR1]

First off, let me say I'm sure Corey's headers are far superior than OBX (not just the fact that they are produced in China).

Quality product from a QUALITY ZR-1 tuner in the US!!!!! Bonus!

As far as saying OBX / Stainlessworks headers are going to give you far less "RWHP" or MPH (in the quarter mile) is doubtful.

Brad is comparing two different cars and not the "same" car. In order to get a true comparison, you must install OBX/Stainlessworks and dyno the car. Then uninstall and reinstall Corey's headers and do the same test.

I have StainlessWorks headers (relatively happy with it), but if Corey was making his a few years ago.... I would have purchased his!


Love to see a "true" test of all of the headers....

dominic , what i did was i dynod the car with the stainless works/ obx style then went and took off the headers of the 90 which has a blown head gasket ugh . and put them on the 92 and re dynod the car 2 day later on the same dyno and the car made 17 more rwhp and 6ft pound of tq more than with the stainless works set up . the only thing that was changed was the headers . what i found was the stainless works /obx headers primary pipes ranged from 10in to 24 in and the collector really pinched off where the primary pipes ended into the collector . in fact when i took the car to coreys a couple of years ago after putting headers on . the first pull on the car only netted a 3 wrhp difference 372 was stk and 375 was the first pull . corey did his magic and got it to 389rwhp now granted it was 2 different dynos. but it no where came close to the improvement i got from my 90 when i installed the jeal headers. that car went from 331 stk to 368 with just the header change . those tests where done on the same dyno but 1 month apart. the jeal headers primary pipe lengths were short 22in -24 in and the collector was a true collector not this pinched off thing. . also when i started taking the 92 to the strip the car trapped 112.6-113.2mph stk and after the install and coreys tune only went to 114.9-115.6 . i found extra power when i changed out the corsa which was on it stk to a 3in xpipe then went with the stk 23/4in pipe to 3 in super turbo mufflers with dual exits to keep a stk look . it now traps 117.5 118.6 depending on the da that day(that was still with the stainless headers ) . i have g teched the car with the jeals and it is up almost 2 miles ann hr over the gtech runs with the old setup . i hope to try to find some time this next month to validate my g tech numbers with real drag strip numbers . . to give a hint my 90 which only has coreys porting tune jeal headers and dr gas 21/2 exhaust trapped a high of 119.47 miles an hr . the da that day was almost 3000 ft . the 92 has the callaway porting in the inj housings and plenum and also has porting done on the heads .. pete was telling me that the callaway porting was not very good .soon as i get strip numbers i will post the videos and slips for everyone to ck out and decide for themselves which way they want to go .


Did you get a compression test right before the dyno pull before the head gaskett blew. I wondering if it was failing during that pull?

Dave

[sammy]

the head gasket failure was on my 90. the comparison tests were done on my 92 which is running fine . decided to switch headers as it will be a while before i can get to fixing the 90. work this time of year is a 16 hr a day deal .

[sammy]

First off, let me say I'm sure Corey's headers are far superior than OBX (not just the fact that they are produced in China).

Quality product from a QUALITY ZR-1 tuner in the US!!!!! Bonus!

As far as saying OBX / Stainlessworks headers are going to give you far less "RWHP" or MPH (in the quarter mile) is doubtful.

Brad is comparing two different cars and not the "same" car. In order to get a true comparison, you must install OBX/Stainlessworks and dyno the car. Then uninstall and reinstall Corey's headers and do the same test.

I have StainlessWorks headers (relatively happy with it), but if Corey was making his a few years ago.... I would have purchased his!


Love to see a "true" test of all of the headers....

:cheers:

Davidi am sorry maybe i didnt write it correctly . the comparison was done on the same car . i took the headers off the 90 as the head gasket was blown on that car and put the jeal headers on the 92 . the power difference was to the 92 car . it made 17 wrhp more and 6lbs of tq more with the jeal than with the stainless works /obx design . all dyno runs were done on the same dyno on different days.also it was just a little warmer on the tests with the jeal headers . we did 4 pulls on both tests . all pull were within 4wrhp of each other .the only change to the car was changing the headers , i used the same exhaust that was on the car and didnt do anything in the way of tuning the car . it allways buged me that my 90 made more power with just with just headers and inj housing and plenum porting than my 92 which is a callaway 475 super natural . this motor has ported inj housing plenum and heads ,as a part of the callaway 475 pkg . next i want to put coreys ported inj housings and plenum thats on the 90 on the 92 and see what the difference is .

[boostedmaxPSI]

Excellent thread Sammy. I emailed Corey to quote me a set of his headers. I'm ready for a set and based on your findings this will be the direction I will go. I will remind him to send you a commission check ;)

[ZR WON]

All:

Been a long time since I was involved with headers, but I did have something to do with Stainless Works design. And I can tell you that Billy Kirchoffer (sp) originally started the process by having SW's pattern a Jeal header (which was a copy of the original Watson design, only utilizing one piece primary pipes). He stopped communicating with SWs and I picked up the ball and ran with it about a year later. Someone mentioned Corey's headers being longer than SWs. That's rather confusing to me.

If that is true, Either Corey has changed the design of the original Jeal's, or SW's has changed the design of it's version. As mentioned, the original SWs design, with the exception of the 1/4" flange (which was changed to 3/8" after about 10 sets were completed), looked exactly the same, and performance was the same. I have them on my car and it makes@400rwhp with Corey's port work. Which begs the question: How on earth does Jeal's design make even a couple more horsepower? I could see the difference maybe varying 2rwhp due to natural variables, but 12? That's rather hard for me to believe.

Is it possible that some people are confusing the OBX 'short tube' design as being similar to SW's? Again, maybe SW's redesigned their header to be a 'short tube' design, but I rather doubt it. Finally, I'm all for Corey getting the business, he's a great guy with a lot of talent and a true ZR-1 lover. SW's, while also a great company, produce products for *all* cars. I'm simply trying to make sure everyone (myself included) has accurate information re: various header designs.

Pete:

How's it going? Been a long time. I am not refuting your installation experience; at this point you've done many more than me. I'm simply trying to make sure everyone has accurate information. What's confusing to me is Sammy typed that his SWs looks just like OBXs design. That leads me to two possible scenarios: 1) SW's changed it's design and are now selling 'short tube' headers or 2) Sammy is mistaken.

I have a set of Watsons and SWs somewhere (in the attic I think ;) ), and also have photos somewhere (which I can't readily find ;) ). What I can tell you from memory is the Watsons and SWs look *exactly* the same, sans the former having the primary tubes pieced together and welded. And Watsons are a true long-tube design (as are Corey's/Jeals). There is simply no way that a Watson/Jeal/SW design header is going to have a 12rwhp discrepancy between them. Now, a short tube design like OBX? I can totally believe it.

Anybody got a pic of the Jeal/Corey headers. How long does a long tube header have to be to be a long tube header? -Steve

[ZR WON]

Here are the photos I have for the various headers (Jeal, SWs, Watson, and OBX, respectively). As you can see, the Jeal/Watson/SWs likely have an additional 2-3" worth of pipe in comparison to the OBX design (the Watson photo is of the 1-3/4" primary version, which is quite rare). As mentioned previously, I could see how the shorter tube OBX design wouldn't produce the power numbers of the Jeal/SWs/Watsons.

Also, I ran out to the garage and measured the primary length on my SWs on the drivers side (couldn't get to the passengers) They are:

#1: 25"
#3: 21.5"
#5: 19"
#7: 16.5"

Unless Corey has patterned his 'new' headers after the one of two truly equal length primary header sets ever manufactured (by LPE), his are going to measure roughly the same. I don't own OBX, so I cannot comment with actual measurements, but based on the photographic evidence, they are visibly shorter.

Just checked my OBX. #1 is about 25" to the clamp, #3 is about 19" to the clamp. the rest were too hot to reach into.

[ZR WON]

Clamp?

My measurements are taken beginning from the primary coming out of the flange, ending where the primary tube goes into the collector. I'm sure sure how the clamp could be over the collector so far that it's touching the primary tubes, but perhaps I don't fully understand how the OBX version connects to the cat/exhaust. If they are in fact the same length primaries, the photo I have is quite deceiving. They definitely *look* shorter.

I got probly 19 or 20 if I just measure the tube. Do you think longer makes that much differance? I'm assuming longer means less interferance from cylinder to cylinder.

Longer tubes better exhaust scavenging
Which makes more power. How much more?
Very hard to say, maybe 10hp, perhaps less.
Better still is Equal length tubes, but there
were only two Sets of equal length LT5 headers
made (by LPE). I know where one set is, it's hard to

I have one set of equal length headers on the 427. Primary tubes are 2" dia, 28" long. Has to have custom exhaust, nothing out there will bolt up. No idea who made them exactly, but were told they came from the Kim Baker / GM program in the 90's.

So it sounds like the quality is decent. About how much power do these headers add?

[KILLSHOTS]

Along with the proper tune to add fuel, Marc says they add 25+ HP. Not sure I felt a full 25 HP on the butt-dyno, but it's definitely a worthwhile mod.

My second ship from Marc was only for 2nd deletion, I think. I could tell I was getting a little more twist; I'm guessing about 20 - 22? Maybe as much as 45 dB http://www.zr1.net/forum/images/icons/icon10.gif

Yep, those bullets that come with the OBX are just for looks, they're not cats at all. I guess they're meant to help with a visual inspection in states where that matters.

You should definitely send the PROM back to Marc. When you do headers, he adds fuel to support them and enables the anti-backfire. Until you do this, you won't produce all the power that adding headers allows. Marc does keep excellent records; that's how he was able to figure out that he hadn't enabled anti-backfire on mine without even having it in his hands.

[efnfast]

Glad the OBX came with the psuedo cats, in NH all we need is a visual inspection and the check engine light can't be on.

Maybe I'm crazy but I feel like 311 who is low for these cars. I have seen a lot of numbers around the 350 mark for a stock car.

393 WHP is impressive though. I bet it moves rather well and the LS guys probably have a hard time keeping up. Haha

Now that the water is gone from the tank, it's running and idling smooth as ever, again, (except for that 1.6 - 2.4% TO glitch, which I don't believe is anything wrong (and that Marc says they all have http://www.zr1.net/forum/images/icons/icon5.gif ) ).

Man, have him add the fuel and just ask him to not disable the DFCO. You're lucky to not have the backfire issue; Marc told me mine was running unusually lean on decel anyway, before I made the modifications, so it doesn't surprise me that mine was backfiring like an SOB. Marc feels strongly that you need to add the fuel to get the full benefit. Enhance that Permagrin, Schrade!

It's my understanding that Corey doesn't build the Jeal header unless it's part of an overall engine build. Just not worth the time and effort as a stand alone product.
