Ok guys, I know that this has been asked before but know one seems to be able to answer my questions or are they not happy with you welding products to your car and then giving them back
well u can't have sound and performance. I have the klze swap and soon to be supercharged and I am going with a 2.5 inch with 2.5 inch highflow cat and resonator. that is the best for crisp sound and emission purposes. it also only holds back about 1 to 2 hp.

errr...I would perfer to get custom 2 inch straight pipe done. Then get a good quality muffler. (apexi, ractive, arospeed, or whatever you perfer) . I've heard that the pacesetter catback will rust away after a couple of years. But this only my opinion.
just get some mandrel bent piping...2.5 and a nice muffler....I would suggest a 5 zigen firball but what ever floats your boat....oh ya dont' go straight pipe and no cat it will sound like s--- and will be bad for environment...and dont' gut your cat cause it actually subtracts hp's because it creat's more turbulence in exhaust flow...not to mention it sounds like crap....ricers my think it sounds nice....
