I've read a few places that the 2012's come with a stock CAI and a decent flow on the headers tubes and mufflers...the car sounds decent exhaust wise but i feel that adding a CAI would add to performance...probably going to an airraid and a tune to 87 octane...also i noted that adding an exhaust wont really add to any gain....except for just changing the exhaust not e little bit...anyone else heard the same thing?
