From Experience
I'll tell you from experience, cussing people out is not the way to get what you want. I'm a youngin (14.) I got my car about 3 months ago. Before I ever got it, I spent countless hours reading up on different things. I could name a lot of stuff on my Z the day I got it. I got the FSM about a month later and read up on that. I'll tell you, I don't know everything, but I know quite a bit about my engine.
An old trick my dad taught me, turn the cover for your Air Filter upside down, or if it won't fit, cut a piece that'll hold the air filter down. Once you get on that baby, it'll roar (if sound is what you want.) It doesn't sound rice, sounds deep and powerful. If you don't have money to redo your exhaust, but want more than stock, cut off the tail-pipe right behind (back) the muffler. It won't be straight, so it'll pass emissions, but it'll sound pretty good.
Anyway, as everyone have said, there's people on this site who will be more than happy to help you out if you've got the right attitude. Remember, this ain't school where you can talk sh*t to get what you want.
