Im looking to upgrade my stock exhaust on my 03' GT, but im not sure which to get, ive looked at mostly all the companies who offer cat back systems. I want to get the system that offers the best performance gain, not necessarily the best sounding....someone give me some advice
the catback isnt the part of the exaust that will give you the most power. if you want to add the most power get an o/r midpipe, or some LT headers. you can do a search to find more specific info, but most catbacks give you around the same amount of power, i would chose a catback based on sound rather than worring about power. get a midpipe and Lt headers for power.
there isn't much difference between exhaust as far as power goes. cat bak give you 1 or 2 hp between bad and good catback. I'll go with something that is straight through set up(i.e. magnaflow or SLP) rather then baffled(i.e. rustmaster or Mac).
And get mad prochamber, you'll love the sound, and small power gain you'll get from PC
