Did the OBX headers fit or what???

[carter200]

What is the final results on the OBX headers. Deal or not??? Inquiring minds want to know.....

[Kb7tif]

On the other forums on c-5 c6's people are using them and haven't heard a bad thing yet as a matter of fact some were impressed with the welding ect.

I Think he means on the ZR-1.

A member here bought them and was doing the install on his Z.

You are exactly correct. You would figure by now the headers would be on the Z or sent back. I'd like to know how they worked out......:icon_scra

I don't hink he has had a chance to install them

Just received the set I ordered last weekend, and they look like a really good quality header. They took great care in packing them, and included header gaskets with them. The welds are all very clean, and the individual exhaust ports look like they've been cleaned up by hand. Even if they are quite as good as SW, for the price they are a very nice product, and have to be WAY better than the stock 91 manifolds that are on my car right now.

Have to get them coated, and then take the car down to Corey's so, I probably won't have mine on for 3-4 weeks, but I'll make sure to post Corey's impressions when I get it back.

you're going to powder coat your headers? :icon_scra

[-=Jeff=-]

my guess is swain coating or Jet Hot ceramic coating

[carter200]

Thanks and look forward to see what "you" think of them. The fit I'd like to hear what Cory finds out.

[mgbrv8]

The Tranny is in my drive shaft is rebuild, I started on some beam plates, and I removed the old factory headers(That was a BI#%CH). But I have not touched the OBX headers yet for a test fit, we have entered our heavy part of our autocross season and I have been swamped with my track cars repair and adjustments.

Dave,
I understand the delay with all you have going on. Another member has a set, too, so between you and him we'll get the scoop on the OBX header issue.
Get ready cause next week the real cold weather will be paying us a visit. Hang tough :cheers:

That's why I live in the southern tip of Texas all we ever have is sun and warmth in varying degrees. Its also the reason why I have so many projects ;). You never have too shovel sunshine.

What's real cold there? 30deg?

it was -4 here a couple weeks ago.

ceramic thermal coating

High of 17 is a bit much for central Texas.

When I was in Tech school in Chanute I can remember marching with a leather face mask to keep my face from freezing. Now that was a bit cool by Illinois standards. :mrgreen:

[-=Jeff=-]

Wow it gets that low in Texas? Neverwould have thought that

[carter200]

Does not stay that cold for very long but with the added wind chill factor it sure gets your attention. Sure makes me appreciate the kerosene heaters in my shop. Keeps it a toasty 60 on the very cold days. Working all day while seeing your breathe is a real experiance. I know this deserves a :-({|=

here is a little update
Dave

[carter200]

Dave,
Thanks for the update and looking good. What is the "pipe" welded onto the pipe in pic #8? Nice work!

[mgbrv8]

Its a air tube port I think. I ended up machining a stainless plug in the lathe and pressfiting it in and then capturing it with a pin. Only one of the headers has one, the passenger side.

Dave

[carter200]

Thanks. Thought that might be the reason for it but was not sure. So there is nothing to hook up to it? What year are you putting them on? Thanks again.......

It a 91, speaking of which I need to get off my butt and get wrenching.

Hey how did they sound and what exhaust do you have??

dave

[ZR1@gmx.com]

They sound great! Nice throaty sound, I have flowmaster exhaust. I could feel the additional HP too! Very happy... I will post a few pics...

How I shortened 3 of the bolts to fit below tight bends

Slotted the flange below the first pipe on the right side.

George's custom dip stick was the icing on the cake!

The Bosch aftermarket o2 sensor came with 18" leash and custom splice block that took care of the need for extension on the right side... Did not have to unplug the connection, just cut wire and splice. left side fit with no extension.

I used the stage 8 bolts and was able to get all 32 in with the clips, they worked great and were economical.

[carter200]

Nice and glad they worked out for you. Thanks so much for the pics. :-D

[Torchred96]

Wow, don't know how I missed this. The pics look awesome. Is there any update on performance or issues with them? Looks like another affordable mod for the Z

Thanks

[Kevin]

if i can't find a used set of headers i may go with these

[limey]

Go with them, i've sold a few sets for customers and everyone fit perfect.

Excellent value for money!

They also have the full exhaust now, anyone tried on yet?

[XfireZ51]

Why did it look as if the D/S header hung lower than the P/S in one of the previous posts? I am assuming these are 2" primaries?

[Torchred96]

How hard are the headers to install? Are all the bolts accessible and what type of bolts are those that you used?

thanks

[Blue Flame Restorations]

I just bought a set of OBX's and I plan to have them Jet Hot coated.

[secondchance]

I installed a set of OBX, with WAZOO help, on a 94. I love them!
I had a chance to compare OBX to SW side by side. All tube bends are pretty much identical. Only difference is OBX collectors are about 10" forward and OBX comes w/ glasspacks that looks like metallic cats. These glass packs can be replaced w/ metallic cats if needed w/ minor mod. Cats should work better since being closer to exhaust ports should heat up better.
Quality is as good as any other headers I have seen.

[Blue Flame Restorations]

Did the dip stick tube need relocated for OBX?

[secondchance]

Did the dip stick tube need relocated for OBX?

I assumed that it would since we used a relocation piece when we did the last install which was SW.
Yes - I used a relocation bracket and all went smoothly. Also used Stage 8 bolts.
By the way -do yourself a favor and get a set of gaskets from Jerry's. OBX gaskets are 8 rectangular individual pieces - one per port. Got to be a real PITA to use.

Thanks for the tips. Pete will be doing the install, so I bet he already has a parts list for me to buy.

Cool! I am sure Pete is well prepared.
I am so impressed w/ OBX header quality I just might try out their stainless steel exhaust too.

I saw their exhaust. Good price. Just don't know how restrictive it is??????? Looks nice.

[Torchred96]

Hey Kevin, why would you look for a used set...they sure arent going to be any cheaper than these. The way I see it, a company that makes a quality product at an affordable price is a win win for all. why not support them?

Secondchance, thanks for the tips and report.. These are definitely on the buy list as soon as I get the top end finished.

[Kevin]

mostly because I need cats. I've got a line on headers/cats for $700ish and I'm just hoping the hold out till I have money to buy them.

if not, I'd consider these. but I can't pass inspection without cats...well I can but I'd rather not have to find the a guy to lick and stick my car.

R U looking for stock

that's what's on the car now. looking for headers/cats but not just now

[Torchred96]

I just sold my lt4 sw headers with bullet cats for 750. I bought them for 900 second hand 4 years ago. The cf member I bought them from said the cats cost about 200 a piece.

If it was me, I'd take advantage of these headers now (sounds like i'm sellin em doesnt it?) and keep an eye out for bullet cats. Lot easier to come up with it in portions 500 headers+ 400cats later then to come up with the whole thing at once.

In fact, I bought the lt4 headers in 3 payments of 300, and sold them for 3 payments of 250. It was the only way I'd ever be able to own them.

[secondchance]

Jim tells me he has located and ordered a pressure gauge that can be hooked up to a 02 sensor bung.
We at the WAZOO land have an assorment of headers and exhaust systems.
We will be hooking this gauge up to various systems, measure pressure present at 02 sensor location and post our result I am sure.
Bear in mind, though, the lowest back pressure does not necessarilly mean the most hp.
Under the circumstace, I must get an OBX system to comare to others - factory, Corsa and B&B.:cheers:

A lot of SW headers are the same way,one side sits lower then the other,who ever has SW headers go look under your car.
From what i remember it was the early SW headers.
These look like shorty headers.

Yup! As you implied, exhaust flow dynamics is a comprehensive subject. Being successful after considering just one component, that success is in spite of research, and not because of it.
I'm just sayin.
