Just purchased my brand new 2012 STI 3 days ago and still haven't even broken her in yet but in the future I do plan on doing some aftermarket additions to it. The dealer was very vague when they say what would and what wouldn't void warranty as far adding performance parts to the car and I have heard different things from numerous people. I really want to make her purr with a new exhaust (which they said wouldn't- only things that would are adding pipes that directly come of the engine itself like up/down pipes, wiring, air, and messing around with the ecu/computer). I have also heard that if i were to get an exhaust that i would need a tune, which i would assume would void warranty? Anyone here have any knowledge about this stuff?
And, if i were to get an exhaust, which are some good brands and what not. I am not willing to nickle and dime this car and would rather pay the extra money for a better performing exhaust.
