OBX cat-back exhaust

[secondchance]

Looks like OBX is getting into cat-back exhaust too. Looks a lot like Corsa.

nice price for a Corsa system.. LOL

Looks like Corsa anyway

[FU]

That set up in a TRUE 3" would be the ticket.

[ZZZZZR1]

Wow. That's an insane price.....

It does look like Corsa!

Yun, are you buying it????? I can't wait to inspect it

Nah... I am splicing on a Magnaflow w/ LT1 tip.
It seems someone who knows a lot about ZR-1 is advising OBX. Them boys know what we like.

[GOLDCYLON]

Wow looks very Corsa-Esque

Did they "Borrow" the stock photo lol

[MikeGolf]

Has anyone pulled the trigger on a set of these yet?

[Kevin]

any idea on how these sound/flow?

[secondchance]

At 6000 rpm, 1st gear, factory registered 1.4-1.5 psi. OBXregistered about 1 psi.
As for the sound it's very mellow.No resonance at 6th gear crusing.
I am very pleased.:cheers:

Did you hook them to stock manifolds or after market headers?

[Corbusa]

wow that seems cheap. Is the quality ok ? I might have to pull a 3rd shift and get this..I also see they have the ZR headers too..

[secondchance]

Jeff - I think OBX is less raspy and more mellow, bassy sounding. About the same or less loud.

Kevin - next time in DC area you are more than welcome to drive my car.

MikeGolf - I am running OBX headers.

Corbusa - quality is as good as OBX. The whole system is polished SS.

[MikeGolf]

Would they hook up with stock manifolds? Thanks for the help but for the price it makes you wonder. I will do the headers later in year but with the coating and everything, I'll need an exhaust system first.

Yes it will hook up to the factory system - at least it would have for my 94. Driver side will hook up with 3 holed triangular flange and the passenger side will mate w/ 2-3/4"diameter pipe (factory size).

[Corbusa]

I have a few questions about the exhaust systems .. The OBX system for sale, will it fit right in place of the factory system or is major mods necessary ? When I do get the headers is there major mods needed there? Especially to hook up from the header flanges to the new system? How does it connect to the cat(s) or resonator..
Which part of the factory exhaust is the most restrictive ? Are factory old cats hard to get or expensive? I was thinking of getting old ones to hallow out so it looks correct yet can breath.. Any suggestions is appreciated..
FYI I am working day and nite to get my vette paid off asap.. But when cheap good mods come available I'll do what I can to get them and set them back for later.. any and all advise it really welcome...

First my comments are based on my experience w/ 94Z. I believe 91 and up are close.

Both headers (OBX and SW) and cat back exhausts (Corsa and OBX) are designed to replace factory exhaust manifold and factory exhaust independent of each other - meaning connection points are maintained so the headers or the exhaust will mate to factory connection points and match the factory connection type (3 holed flange on the driver side and slip joint at the passenger side).
Both SW and OBX system does not account for cats. Factory manifold has cats very close to the runners. Headers, in order to maintain separation between individual exhaust ports, runners do not converge until the collector. If you need to splice in cats, cat has to be added after the collector. This means for SW, cat back exhaust has to be modified to splice in cats. However, OBX header collectors are about 12" closer to the motor and after the collector has a glass pack that mimicks spun metallic cat that slips on between the header collector and the exhaust. These pieces can be used as a template for metallic cats to be modified for splicing into the system. Also, this 12" closer to ports configuration would help in lighting off the cats and keep them hot.
As for which part of factory system is the most restrictive, answer is the rear mufflers at least for the later exhaust system. Early factory exhausts are restrictive starting w/ connection into resonators (a piece in the middle of the car).
If you intend to hollow out the factory cat for visual go with OBX. OBX already includes glass packs that visually look like aftermarket metallic cats.
Call me if you want to discuss or need more info - 703 980 8814.:cheers:

When I get a chance to get my car on the lift I will take a few pics and post.

[secondchance]

Though it worthwile to add more detail:

I modified my exhaust in stages namely due to financial restrictions.
First mod was removing the factory exhaust manifolds including cats and installing OBX headers to factory exhaust - hp and torque increase was immediately noticiable accross the entire rev range. At idle the car sounded the same w/ factory system and at about 2000 rpm became slightly louder.
Then, I bought a pair of Magnaflow mufflers ($259 at Corvette Central) and replaced the factory mufflers - exhaust became a little loder but the car developed droning in 6th gear that gave me a nasty headache. These were removed and sent back to Corvette Central.
Finally I saw the OBX at an incredible price and had to try it - high quality and no issue w/ install - system, including headers, is a little louder and I can hear the engine pulse. Definate power increase over header/factory system at higher rpm and yet quiet enough for a normal conversation and, most important for me, no droning in 6th gear!

I sincerely thank Jim and David for helping and putting up with me going through all these variations of exhaust combo.

[Corbusa]

Thank You sir!, I'm going to see how quickly I can get started on mine.. I appreciate the info...

[efnfast]

This sounds very promising to me. I'll do mine as soon as finances allow. Ceramic coating?????

[secondchance]

Please beware I can vouch for construction quality and reduction in back pressure. But the sound quality (whether you like it or not) is a subjective thing.

Not the exhaust system just the headers. The exhaust system is SS and doesn't need anything done to it.

Seems there has been a lot of discussion with pros and cons on coating headers. Do we the zroners like it and or recommend it?

I recommend headers to be coated. I have seen stainless steel headers after a couple of years of use and they do turn grungy looking. If not for heat retention resulting in hp gain, at the very least do it for cosmetic reason. For $350, at least for me, it's a money well spent considering typical 2 person 6hr (total of about 12 hours) work for installation. I prefer not to do it over.

[Scrrem]

Well, here's a vote for coating...This is the way they will always look...

Thanks for all the input. I kind of highjacked this thread. Looks like when the time comes it'll be OBX headers, ceramic coated and an OBX exhaust. Are those cats on the ends off the headers, or just something that will make the inspection guy think they're cats?=D>

That thing immediately after the collector is just a glass pack disguised to look like metallic cat - hopefully tric inspection guys.

[efnfast]

In NH all that is required is a visual inspection.:dancing:flag:

[DaveK]

Really appreciate the information and feedback on this thread. I'd already bought the headers a while back, just ordered the cat backs to match :)

One question - when you get the headers coated is it just the header/collector or do you get everything done?

[secondchance]

I had the headers, collectors, fake cats and one elbow - basically everything that came as a part of header from OBX- coated.
One more thing, I did not like clamps that came w/ headers or the exhaust. I ordered, I think, 6 2-1/2" band clamps (for cat back exhaust) and 2 3" band clams (for header collectors) and one 2-3/4" band clamp for fake cat to sleeve for driverside - all from Torca Accuseal. Also, I used 2-3/4" wide band clamp for connection between the driverside header and driverside exhaust. These wide band clamps (for slip joint not butt joint) do not crush the exhaust pipe so that later on when the exhaust has to be removed for tranny, clutch, or other work, exhaust can be disconnected and reconnected w/ minimal hassle.

I agree 100%. I just installed mine and the clamp they sent suck. DO NOT even try to use them. But other than that, the quality seem fine with sound is better than stock but not to loud (but I am half deaf and like cherry bombs). My car looks funny now with something shining under or on it. But now I can put my originals up in storage.

Do we have a friend we like to buy the OBX exhaust from, or "racing parts depot" on e-bay for $349.00? Any new thoughts on this system? Looks like it comes with a resonator, should this be replaced with an x pipe?

[secondchance]

"X" pipe would have to be custom fabricated. It will certainly give you a few more hp. Also, a little louder.

[efnfast]

SC, did you use the resonator?

[MikeGolf]

I used the supplied resonator but still have the stock manifold and you really wouldn't be looking at that much of a seat of the pants HP gain with changing to a x pipe for the price. The resonator has an H pipe. Maybe when I go to headers it would be worth it. JMHO. :cheers:

Who'd you buy from?

[MikeGolf]

I have no connection to the seller. My only complaint is their clamps as posted before.

I didn't realize the resonator had an H pipe.

It's hard to see in the picture but it's right before the resonator itself.

Thanks secondchance for the info , But I'll probably ( considering) go with the Dynomax mufflers 17228 2x80ish = $175, but a summit x pipe , and 5 sticks of 3 in stainless =$200.00.. Just buy the parts little by little.. Then get the obx headers and some cats..
I'd probably go OBX but I dont know what the power loss is from the factory 2.75 pipe compaired to 3" or the obx 2.5... I guess too I need to factor in exhaust tips on the pieced together system I'm wanting to do... oohooh decisions decisions ..:)

Kevin, If I had a stock ZR-1 the choice would be easy to make, For the cost of the headers and entire exhaust you can throw it out in 5 years and buy an entire system and still not be at the cost of the Corsa.
It sounded damm good.

This kit came with resonators.
Unlike Corsa all 4 tips are functional. Corsa has no perforations in side resonators nor mufflers. Instead, Corsa has a port in the mufflwe used to generate out of phase sound wave for noise cancellation. OBX uses perforated pipes inside the resonator and the muffler - similar to old glass packs.
Yes. I am running a set of OBX headers.

I replaced the original one due to being dented at 40,000 w/ another with 10,000 and added another 80,000 - no sign of rust. I believe factory is a SS unit.

[Blue Flame Restorations]

I was looking at the ebay OBX exhaust today. The For Sale heading lists the LT5. When I used their application chart on the ebay page, it says that it's not compatible with ZR-1.

The link you provided also has the LT5 heading but the chart, again, says NOT COMPATABLE. Is this link you provided the one that shows the part number you purchased? If so, and it worked for you, I plan to order the exhaust to mate to my OBX headers.

[efnfast]

Brett, just an FYI. I've been trying to get a hold of "racing parts depot" off of e-bay to buy both the OBX headers and OBX exhaust. I can neither get my credit card to process, nor get them on the phone. Total price including shipping was $839.00 or so for both. Smokin' deal if I could actually buy it.

You will not be disappointed. Make sure you get 6 x 2.5" Accuseal clamps abd 1 x 2-3/4" slip joint band clamp alo by Accuseal.

Hey Yun :wink: a question for you. the 2.5" clamps are for butt joints or slip joints? No I haven't opened the box the OBX exhaust came in yet!:o:sign10:

Why yes I did Brett! :) It was my Christmas present to Mistress this year. It is still in the box along side the box with the s/s headers.....:hal:....someday maybe I will put the OBX exhaust system on as I think I can do that in my parking space...I hope! All I need is a weekend where it will not rain or maybe just one weekend day where it won't rain and I figure 8 hrs of time should get the cat back system in place. :pray It stinks not having a garage!

Hey,

Consider coming down to the WAZOO HQ. Headers and exhaust, we are looking at about 8-9 hours if we move fast. I am sure Jim will offer and I will also jump in. We've done 3 or 4 sets of headers.

When I wrote this I id not see Rickey's post. Either way...

[tomtom72]

Yun and Ricky, ya know that the attitude that Z Brothers have toward one another where helping each other is involved make owning one of these cars special. You guys are tops! :thumbsup:

I have to open up the boxes because I remember when I looked in the header box, they came with those really wide s/s band clamps. Looks like my living room floor is going to be the "mock-up room" this weekend. It's nice to be single sometimes!:sign10:

I will do an inventory of what I need to order and get that order placed. When I have all the "extras" I need then I'll reach out and see if the WAZOO will allow an interloper into the skunk works.


Steve, I'll wager that you have yours on before me! Anything but the simplest of maintenance for me is a real PIA. My Z lives in a rented garage space about 5 miles form where I live. In theory I'm not allowed to detail the car inside the garage! They kind of put up with that, as it's a whole lot better than what I used to do before I was informed of my transgressions! The garage is in a Co-Op building so they have rules!:eek:

Paul, thank you for being kind to me! :thumbsup:

I have one of the dipstick tube brackets that Jeffvette made. He gave it to me when I bought my headers.

Thank you very much for thinking about me having all the parts I need to do the header install!:handshak:

This is why it's so great to be a part of this Brotherhood! I could not even think about owning a ZR-1 without being a member of our Registry! It would be scarier than an IRS audit!

Tom, hopefully we both have this done before BG, and hopefully we can still hook up for the ride. Bitch having the car so far away, mine lives in a heated (and air conditioned ) garage at the house, but my abilities are certainly limited. I need to tear into things so i'm not so afraid of them. My down side is my driveway is about 3000' of dirt, then a mile of dirt road to the tar. Long ride in first gear at an idle.
:salute:Steve

[oricale]

Hey guys I ordered through them and recieved it,..I may need the Bracket as well....!! I will have my car done by BG!!!

[efnfast]

Glad to hear you recieved it. Hopefully mine will be along shortly.

[Paul Workman]

Glad to hear you recieved it. Hopefully mine will be along shortly.

Post office said "prolly Monday" on the bracket.

As for the dirt road, buddy, I hear ya!! I used to have a black 95 Vette before getting the red Z. The one good thing I got outta 5 years of owning that car was ZAINO. Nuthing like it for shine that shrugs off the effects of sun and dust.

[efnfast]

Thanks Paul, I have no doubt the bracket will show up. I was refering to the exhaust, that I'm worried about. I'll beleive it when i see it. I had problems processing the order.

:mrgreen: <--- I'm green with envy Steve! I better not let my car read your post because she lived in a climate controlled garage until she got sold into slavery and I bought her. She might get mad at me.....but Mistress does get plenty of fresh air and exercise since she's been with me! I'd kill for a 20' x 10' unheated garage with a dirt floor!

I may get the cat back done before BG. It depends upon if and how much of the system I decide to coat and who's coating I decide to use. God I hate budgets! Either way, with or without the exhaust I'll be at BG though, you can make book on that!
:cheers:

[tomtom72]

Okay, for real this time I unpacked all my Mistress' presents from all the recent Christmas's past! You didn't really think I put Christmas lights on my headers every year, right?:razz:

my photos are here: I thought it appropriate to put the stuff in Carter's album, although I'm sure Carter does prettier welds!

http://s215.photobucket.com/albums/cc123/tomZR1/1-31-12%20%20%20CTMachining/

I have some Questions for the exhaust experts.
Is the right side OE CAT exit 3" on our cars? I ask because on the S/S wks CAT seems to be and the bell on the OBX pipe only allows the CAT ball about 5/16" to a 1/4" of depth into the OBX bell connection. Is that going to leak?

The OBX clamps have cheesey hardware so I think in the long run the Accuseal stuff is the way to go. But on the left side CAT exit the OBX supplied clamp seems to be a better answer to the connection than the Accuseal supplied by S/S Wks. The A-seal clamp is a single band clamp, and the OBX supplied no-name clamp is a stepped type double wide band clamp. What does the brain trust think about that choice? Which would you use? I say the cheapie clamp looks to be better suited for the connection, no?
Disclaimer: I haven't looked through A-seal's line up yet to see what they have for sale. Personally I would have liked wider bands on the clamps? Or am I looking for monsters under the bed?:confused:

This question is a bit more esoteric, would you coat the OBX system at least back to the muffler connection to keep heat radiation down into the cockpit and to keep up the stream velocity?

TIA
Tom

A-seal clamp in place on left side CAT to head pipe connection. The OBX supplied clamp is to the right.

http://i215.photobucket.com/albums/cc123/tomZR1/1-31-12%20%20%20CTMachining/SSWksHeadersAndOBXCatBack013.jpg

The same connection as above, only with the OBX supplied clamp used.

http://i215.photobucket.com/albums/cc123/tomZR1/1-31-12%20%20%20CTMachining/SSWksHeadersAndOBXCatBack004.jpg

This is the connection I am concerned about, the S/S Wks CAT meets the OBX head pipe.

http://i215.photobucket.com/albums/cc123/tomZR1/1-31-12%20%20%20CTMachining/SSWksHeadersAndOBXCatBack007.jpg

you can just see the pencil line for the depth of the connection.

[Blue Flame Restorations]

Tom, I think that coating the at least the headers, would be the way to go. I'm crying uncle on $$ and will not coat my headers AT THIS TIME. I have a long jorney ahead and will take them back off and coat them before the job is done. Silly, I know but hey, my money tree is getting sparse!

The pipes back to the mufflers would probably not cost all that much to coat.

Brett, I agree about the money tree....mine is more than a bit sparse! Since I don't have a garage I have to make this right the first time as there are no do over's. My brain tells me that swain tech coating on the headers is the way to go, yes their price is ouch but ya get what ya pay for. Fortunately I can wait on the headers because they're not ready to be coated I have to allot $$ to get the A.I.R. tubes added, then they can be coated.

The CAT-back system is where I'm less decisive. I know s/s is a lousey insulator, and it will be as fast as the OE system at letting heat escape. The hot rod fact is that you want to keep heat in the gas stream so the rest of the pipes should be coated for optimal performance gains. A side benefit would be to lessen the heat in the cockpit. Besides, I'm probably going to paint the mufflers & tips chassis semi-gloss black to keep the OE look I like at the back of my black car....the OE exh is barely noticeable and polished s/s is going to stick out like a neon sign. I'm not much to the bling thing! LOL

[ScottZ95ZR1]

I have one of the dipstick tube brackets that Jeffvette made. He gave it to me when I bought my headers.
:cheers:
Tom

Tom: You may have an extra dipstick tube bracket when it's all said and done as I sent you a PW special with the stage 8 bolts.

[tomtom72]

Oh thanks Scott! Then I will offer the extra back into the general spare parts inventory to be paid forward when a need comes up.

I have a question for you as I figure you have already done headers on a Z. Would some blue lock-tite and regular s/s lock washers be okay to use in place of the special locking tabs that generally come with the stage 8 kit?

TIA
Tom
:confused:

[ScottZ95ZR1]

That's exactly what I did Tom. I did not use their fasteners or washers, for that matter. I only used their bolts with blue loctite. The thing I like the most about their bolts is that the smaller hex-head is easier to work with, for me anyway.

I had the same header kit as you have from the group buy David set up. The problem I had was that the small pipe coming off the passenger cat was about an inch too long, so I had to have an inch taken out of the middle of it. JVD posted here with the same issue with a kit built for stock mounting points. Nobody has reported the problem recently, so perhaps SW shortened the pipe a bit since then - but you have an early set. Hopefully you'll not have that problem!

Yes...if you are speaking to me Scott...I have a set from the original group buy from the new jigs. But on the 90's and proly the 91's & 92's as well, the driver's side is where the short pipe ( 6" long ) goes. Our ball connection is on the passenger side cat. The early cars had the cats welded to the manifolds instead of being flange bolted in place on the 405 motors. I wonder how tough that metal is to cut just in case....hummmm. Oh well I guess I will find out eventually! LOL

Brett, just an FYI. I've been trying to get a hold of "racing parts depot" off of e-bay to buy both the OBX headers and OBX exhaust. I can neither get my credit card to process, nor get them on the phone. Total price including shipping was $839.00 or so for both. Smokin' deal if I could actually buy it.

Steve:cheers:
:salute:

Hey Steve. I received my OBX exhaust today. Pretty quick shipping and it's all in one undamaged piece. Hope yours arrives soon.:handshak:

Don't know yet. it'll be a couple of weeks before the car goes to Pete.

[efnfast]

I did get my gaskets, thanks Jerry. And I got my dip stick bracket, thanks Paul.
Thanks to everybody for filling me in on what I needed and didn't know about. I'm sure it will make the install easier.

Steve

[efnfast]

Headers and exhaust arrived today. Yay.:-D The drivers side (I think) has an O2 bung and the passengers side (I think, they're at work and I only had a second to look at them) has a short pipe for the air pump? Is there only one hookup for the air pump?
Do I reuse the old exhaust bolts? they have some kind of spacer, or crush sleeve on them.
Put a grin on my chin.:dancing:dancing

:flag2: Steve

[secondchance]

There are O2 bungs on both the driver side and the passenger side.
Short pipe facing forward on the passenger side is a hook up for the EGR (exhaust gas recirc.). I believe early cars did not have EGR. Mine is a 94 for I had Marc disble EGR when he burnt a chip for me and plugged the hole.
think you can reuse 3 bolts/nuts but just in case I suggest you get 3 sets of bolts and nuts.:cheers:

[Blue Flame Restorations]

Glad it arrived, Steve. :cheers:

[efnfast]

So, here's the latest. OBX headers and exhaust arrived.

Welded up the EGR port on the header. MY 1990.

Headers left for Swaintech today to get coated.

Dipstick relocation bracket in hand. Thanks Paul

Jerry's header gaskets in hand. Thanks Jerry

Stage 8 header bolts on the way. Thanks in part to Dynomite.

Hopfully I can dyno test it before and after exhaust install.

Did I forget anything? Thanks to the brotherhood for filling in the gaps for me.

Will keep you posted.


Steve:cheers:

[Corbusa]

Hey EFN , thanks for the info.. I'll be fallowing exactually what youre doing... I thought I'd have the extra cash flow to get it done , but found I need ball joints for my work truck.. All this info is Great....Thanks Guys.

[MikeGolf]

EFN have you ordered different clamps or are you going to try the OBX clamps?

[ZZZZZR1]

OBX prices jumped to $459.

I bet they will settle @ $500 like the headers.

[Corbusa]

sshheeezzzzzzzzz Up $130.00 Thats because they know I want the set-up..

[FU]

sshheeezzzzzzzzz Up $130.00 Thats because they know I want the set-up..

The price is up due to inflation in China.

[efnfast]

I'm going to use the supplied clamps, they look so much like accuseal's, I can't see spending $10 apiece to buy clamps I already have. The only differance I see (looking at an online picture) is the bolt.
I think, but am not 100% sure yet, that I will weld some of the parts together. I'll leave joints in key locations for disasembly.
Everything is going up. Priced some PS2's in December from Tire Rack. $226 each. Just went to buy them.......$379.

Steve

[tomtom72]

Steve, I too will be using the supplied OBX clamps. The bolt & nut and the band are of a very low grade of s/s, if they are s/s at all. Try a magnet and you will see that it will stick, lightly, to the components. I tried the test on the Acuseal clamps that came with my Stainless Works headers and it just will not stick at all.

At the worst i may go to the marine supply stor and look to replace the nuts & bolts with real s/s ones....maybe.

:cheers:
Tom

[SteelBlueZR1]

Just ordered the OBX cat back exhaust for only $320 - directly from Racing Depot's site and saved $29 off their ebay store! Go to - http://www.racingpartdepot.com/servlet/the-4854/OBX-Dual-Catback-Exhaust/Detail

Also, per Yun's instruction, ordered the following clamps... Thanks Yun for letting me drive your amazing Z to hear how deep toned and livable this exhaust is on an LT5:

You need 6 of 2.5" Torca Accuseal (stainless steel) - http://www.verociousmotorsports.com/...Exhaust-Clamps

1 x 2.5" Torc Tite Clamp -http://www.verociousmotorsports.com/...-Exhaust-Clamp

[efnfast]

Bert, I was unable to get a hold of Racing Parts Depot directly. I tried. I did use some of the clamps they provided, but welded some of the joints. Left just enough connections to be able to remove it. So far, real pleased with it. I think you will be too. - Steve

Tom,

Do yourself a favor and get Torcas. OBX supplied clamp while torquing the bolt sheared off on me. Replacing bolts and nuts may be a solution too.

[SteelBlueZR1]

OBX exhaust for my Z just arrived, and it is a thing of beauty... Nicely made, good welds, and delivered in 1 week from California to MD. I am hoping to install this Saturday for my Birthday. Yun / Jim are you by any chance available? I will record stock exhaust and OBX exhaust video clips and post, along with some in car audio while driving.

[QB93Z]

I will be in Philadelphia for a wedding Friday and return on Saturday. How about Sunday to install the exhaust?

Jim

[SteelBlueZR1]

Thanks Jim... Sunday is actually my birthday, so that works great. What time in the morning is best for you? I will bring a truck later in the week to pick up my oem exhaust for storage.
I hope Yun and other Wazoo members can make it too... I'll bring the cake. I have the Torcas clamps too, but got a 2.5 instead of a 2.75" for the header pipe connection, and Yun said he has a 2.75 he can trade me.

[secondchance]

I will make Sunday - most likely.

[SteelBlueZR1]

Hey Yun... can you please bring the 2.75" Torc Tite Clamp to connect the head pipe, and i'lll give you my 2.5" that was ordered in the wrong size? I appreciate all your help and encouragement with this purchase/install. Happy 4th of July in Wazoo land!

[tomtom72]

Tom,

Thanks Yun! I may yet do the Torca clamps. No, it's sitting with the headers still in my living/dining room. :o

Actually, now I'm not so sure I will ever get around to putting it on as I don't know that I like the sound. I hate to say this but I have yet to hear any late model corvette aftermarket exhaust that I actually like! Let alone one for an LT5. I like the Ti exhaust sound from the C5 ZO6's and the new C6 dual mode, but the rest of them don't do it for me. I guess I have a differing "vision" of what a C4 ZR-1 should sound like. I actually like the sound of my OE mufflers, when you can hear them up past 5k rpms...it's the damn resonator that stinks! Then sometimes I think I'll just go 'borrow' an exhaust from a DB9 or an F40.....it's the 4V/ DOHC thing that colors my 'vision' of what an LT5 should sound like. I don't want it to sound like my 72 LT-1's factory side pipes. A 4V/DOHC motor shouldn't sound like a 'muscle car' from the 60's IMHO. :o I think I'll do a search as I had an Ansa system on my 72 V6 Capri and I liked that sound.....I'm out in left field, I know! :sign10:

:cheers:
Tom

[SteelBlueZR1]

Tom - I have a LT4 resonator in my garage that can easily replace your restrictive LT5 resonator. It does not neck down and is 2.5"+ internally. I myself have driven an OBX exhaust car and thought it was perfect low deep burble rumble, no resonance, quiet at cruise, not too loud compromise. $65 for the LT4 resonator if you are interested?

Tom,
Nothing wrong with being out in left field or different, at least you did not bring up the bus story........lol. I think different strokes for different folks is what is it all about in this hobby. Thank God that not all of our cars sound the same. We have more Ferraris and high end cars running around here in Yokohama (even more in Tokyo) and I know what you mean the unique and badass sound. Some old school folks would hate that sound. Our LT5s do have a sound of its own, especially at WOT in the near redline that is music to our ears that we can all agree on. :cheers:

You need to come out to the Corvette Challenge in September to listen to some of the LT5 exhaust playing w C6s. Let's see what you think then!

[tomtom72]

...But, but Left field is where the buses don't run Craig! :sign10:

Bert, I hear ya. I was looking for an LT4 resonator, and then I bought the OBX system on impulse. I figured if I really didn't like it I might just graft in the OBX resonator to the stock system and try it that way; or just put the OBX on and use my OE mufflers. I like the blacked out look at the back of my 90. I'd have to think about your offer. I'll let you know. :thumbsup:

Dom, I think I may have to do a mapquest. I figure it's about the same as me driving to BG from NY? I have to see how things fall at work, and I have to save some vacation time to go see the parents in FLA at Christmas. :mrgreen:

:cheers:

Tom,

As long as you weren't on the short yellow bus................

Scott,

Thanks and I can't wait to get this emissions testing over (pass or fail) so I can put the headers back on and install the new SW X pipe, Dynomax mufflers and Pypes tips to so how it all works and sounds.:dancing

When you go in for the next test let us know how close it comes.

Tom,

Thanks for the wishes and you're a really funny guy.

Scott,

Thanks, but it does not seem there will be another test after the news I received today. I still have some air/vacuum leak on the right side throwing off the O2 sensor and running lean from what I am told. I think I'm giving up already with trying to pass.

On another note to not hijack this thread. I helped a guy with an LT1 C4 here bring in an OBX cat-back system today and it actually is a pretty nice system for the price. I guess it could not be done in the US for that price and seems to be of pretty good quality; I was quite surprised.

Wazoo helped to install the OBX cat back exhaust on my 1991 ZR-1, and the installation and fit was textbook perfect. Here are some videos from both outside and inside the car... I am completely satisfied with the quality, look and sound - to me OBX exhaust strikes the perfect balance in terms of deep V8 rumble, quiet drone free cruising in 5th and 6th. The LT5 finally sings the exact song you expect from a an exotic.
My car seems to pull harder in the midrange and part throttle, and just feels all around more willing to rev.
Sorry for the rattle in these videos, as I haven't yet determined where to mount new Go Pro camera, so I held it on the steering wheel -

This exhaust is an absolute steal, and you won't regret purchasing it!
