whats up all u GTO owners out there...Im sure alot of u are having trouble finding perf exhaust for your 05 goat....well if u are i have good news for u.. Right now my 05 gto is at CORSA PERFORMANCE as their test car while they are building an exhaust system for the new 05. The car is almost done which means that they will within the next couple weeks have a catback system out for the 05 gto. So if anyone is interested in their system for your 05....then call up and find out info...cause it will be out soon

I guess I need to get up to speed. I hear this "catback" term used alot. What exactly is a catback and how much of a performance gain is there? I'm actually pretty happy with the sound level and performance stock, but was wondering.

As I've always understood it, "catback" just means that the aftermarket exhaust system replaces the stock system only from the catalytic converters back--not all the way from the engine. That part stays stock.

A cat back system means that it is a completly different exuast with all new pipes from the catylic converters to the end of the car. The sound is unreal. The car sounds like a ferrari while going through the gears slow....a monster while the pedal is down...and sounds more quite on the highway than my stock system sounded..... The power was completely noticable right away....About a 20 hp increase.....and the tips look great too...They are the same tips from the factory....only in a 4 inch ...so it remains stock looking to everyone else....couldnt be happier with this system....great system to buy..
