That's fine, just use that basic information as a better starting ground for searching through threads. It should help you filter through everything a bit easier. If you still don't get it after a little light reading, then we'll be more than happy to help explain things.
Sounds like you should poke around here, start with a cold/cool air intake and go from there. Exhaust will help, but take it to a shop and have them bend up some new pipe with a new muffler. DIY exhaust seldomly works or looks good. Anything else you wanna know is on here...somewhere.
