My GTA's stock exhaust has to be replaced new one.
So, I know the best CAT-BACK system.
Most important point is torque & HP!!
(slp, flowmaster, borla, hooker, dynomax, etc...)

 

SLP for my money the best.

Keep your ride shinning with pride

 

Welcome. IMO it's a matter of what you have now and what your gonna do later. All after market cats flow pretty well, but what you'll pay for is longetivity and that extra 5hp. I gotta Dynomax cat-back for $150. It flows well for what I have, and later I am gonna be putting in a mild 355 at about 330hp. It should still work OK for now. When it gives out, I'll get a higher flowing, longer lasting, more aggressive sounding kit plus a cat & headers. But for now I'm happy with the improvement over the nasty stock system.

 

I want to make my GTA faster than now.
But I don't modifiyng the stock engine.
And, my GTA has a tuned coil spring (a shop in JAPAN made for circuit race)

Please more help.
All of replys are very valuable for me!!!
Thanks.

I helped a friend install a 3" Hooker Competition Catback. It is 3" mandrel bent, dual 2.5" outlets w/ chrome Quads, and it sounds AWESOME. It was only $260 from Jegs.

Thanks GMTech, the help was needed. It was a very simple install(if I would've HAD a cat) so we modified it to fit my off-road pipe. Very well built system and the sound is incredible! I went out driving just to hear it roar. Not too loud especially at idle but it wakes up when you get on it. Here's a picture of it from the Jegs catalog.

For the money this has to be the best 3 inch single exhaust system available. $259!

ONE WORD: SLP

PS you cant go wrong with their liftetime warranty either!

 

Hooker Cat back was 179.00 from Summit with the 10% off and can not be beat for the money! Just put it on this last weekend and it's killer fit right the first time! Except for my header pipe hitting the SFC's
