Most people like to start with the intake and exhaust. I have a Moroso CAI (cold air induction), and it works great for me! Most CAIs give the same amount of power gains.
Exhaust is a tougher one, because of sound. We can't just throw on any old muffler and expect it to sound good like a V8. Flowmaster is cheap, and sounds good below 3000 RPM, but above 3K, it snaps, crackles, and pops when you rev it in Park. Other people like to add I-pipes from V8 cars, and some also buy headers.
I have 2 sounds clips of an accurate sounding Flowmaster. shoot me an email Iceman5359@hotmail.com
