OBX cat-back exhaust - Page 17 - ZR-1 Net Registry Forums

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?

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.

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!

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.

Well said the top end note is outstanding.

Tom,

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 · 07-06-2012

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

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.

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.

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.

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

HAWAIIZR-1 · 07-07-2012

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!
