okay got a question bout my exhaust setup.....i have an aem cai and a dc header....from the header i have 2.25 in piping to the cat....from catback i have 2in piping to a stock muffler (no resonator).... Is there anything wrong with this setup as far as losing performance...this is how i bought the car and it sounds good

You should be fine.
Dont go any bigger on the piping.
If you want a little bit more horsepower; nothing drastic,
get a hi-flow cat and a aftermarket muffler.

^+1 to the Get a high flow cat and an aftermarket muffler. I recommend an Apex-i WS2 muffler. I have one and it's great. Not too loud, not too quiet. And it's not a fart can. I recommend for hi flow cat a magnaflow direct fit catalytic converter. It can be found at partstrain.com or summitracing.com

2" piping should be fine. If you got the money, buy a catback exhaust instead of just the muffler and it'll probably have 2.25" piping and a resonator.

really you'd probably want to have 2.25". IDK why you say to not go bigger.

thanks for the replys i'll be on the lookout for a good deal on the high flow cat.
