    In response to farm rat

A good quality cold air intake helps and someone sells a bigger throttle body too (90mm ?). An '11 can get headers, high flow cats, resonator deletes (there are four i believe) and aftermarket mufflers. A tune really helps so if your gonna do the above THEN get the tune done and the E85 tunes seem to be the cars making the bigger dyno numbers.

I'd check out some vids on the 'tube first though because the exhaust note mostly sounds like crap if done wrong. Like its the spawn from a lawn mower that humped a fart piped ricer kind of wrong.

My '12 is stock since i want noooo extended warranty issues and they blame anything they can for denying you.
