I wanna do a full system... long tubes, hi-flow cats, and a cat back.

So far the only headers I've heard of for the Z06 are TTS's. Are they any good? Are there better ones? Any comments at all? Do they make a decent hp improvement?

I was thinking B&B for the cat-back since that seems to be the most popular. But I'm a bit leery... my buddy has a 2000 hardtop, he installed the B&B PRT "Sport" or something... the mufflers are only 6" long. To me it sounds horrible. WAY too loud, and resonates bad inside the cabin. I don't mind a mild increase in noise... something with a nice bass tone. But I'd still like to be able to roll the windows up and hear the radio, talk on the phone, etc without difficulty. Is the "normal" B&B the same? Any other suggestions for a cat-back?

If you've done a full exhaust I'd love to hear from you... if you have before/after dyno charts or 1/4 mile ETs that'd be great if you could post. My car has run 12.42 @ 113.96 so far (stock)... I'd LOVE to pull an 11.9999999 out of it after exhaust and intake (ok, so that may be a bit optimistic... )

TIA

I had a set of B&B cat backs given to me to try. No cost. At first I loved them, but the resonance became so bad that I hated them. I contacted B&B as well as others did, and B&B replaced them with a new set. Seems they had trouble with the deflector tabs being placed at the wrong angle. They now have a template to assure their mufflers adhere to their standards. My new B&Bs are fantastic and I love them....NO RESONANCE!!

TPIS long tube headers, Random Tech 3" hi flow cats, B&B PRT Quad tips cat back, that is what will be on the 02' Z06. /phpBB/images/smiles/icon_smile.gif

I have to echo Franks recommendation of the B&B's (except I had to pay for mine /phpBB/images/smiles/icon_frown.gif) ). I have over 7000 miles on them and they still sound great. The only change I would make is that I would get the PRT's with the round tips as they would look more like the stock Z06 exhaust tips.

You can't go wrong with DRM's long tubes. www.dougrippie.com along with Corsas. Corsas will give you all the acceleration thunder you want, but on cruise, they are the only ones that will be stock quiet. THE ONLY ONES!!! Even with my mods, when cruising on the interstate, my wife and I can converse without raising our voices. When I get on it though, cops can hear me for miles.

I have Corsa Indys with the GTR tips, and love the sound! But am thinking of the B&B PRT pipes next (need to hear them first).

Cool... thanks for the replies guys!

You need to get the maker of any header to show you some hard evidence of any HP gain. The LS6 exhaust manifolds work very well.

As for catbacks? That's going to be a personal sound choice. The stock TI exhaust works quite well and is light to boot.

I don't know how much of a recommendation this is, but I bought a set of the Z06 TI mufflers from an owner that was looking for sound. The weight savings and better flow over the stock LS1 setup was what I was after.

I did do my homework when making any change. My sources felt the TI was a good setup.

Corsa's sound nice to my ears and if sound is more important than weight? Go for it.

I've heard the Corsa TI exhaust and found it really similar to the Indys.

Yeah I'm probably going to leave the stock Ti cat back on it first, and just do headers and cats. If I don't like the sound then I'll change it. The cat-back would mostly be for sound... I doubt the difference between the stock cat-back and an aftermarket is more than 4-5hp anyways. Hardly enough to justify the expense based on performance that you'll never actually FEEL /phpBB/images/smiles/icon_smile.gif
