Hey, I got my Lancer about a month ago, and I'm DYING to start modifying it. After learning to drive on my dad's Ford Taurus (the one with the DOHC 24V V6 @ ~200HP) and getting the Lancer OZ (at a whopping ~120HP!!!) I want to try and increase my performance.

I already know that one of the first things I do is going to be a cat-back exhaust, and from what I've read here on the forums and elsewhere online, I know the stock exhaust pipping robs the engine of air.

I'm looking to switch to 2.25" piping, but the only cat-back exhaust system I can find that isn't **** expensive has a 3.5" tip on it, and I DON'T want a cannon coming out of the back of my car, because I'm looking to not sound like all the other a**holes on campus (I go to a community college) who modify their cars.

Any suggestions on how to get a good cat-back system without sounding like I have a 454cu under the hood?
