I know some of you have an aftermarket intake and some have an exhaust system and some even have both. My question is which mod is more beneficial for the first mod. I do plan on getting both but for now i only have the funds for one of the two. Some of you say that the intake doesnt make that much of a difference and the same goes for the exhaust. Which mod gives you more power and helps out gas mileage? The intake or exhaust?
