Getting license soon. Job=income. I have money set aside for a year of insurance and around $1000 in gas money. All money I earn is for my hobbies now.

Everything is stock right now. I love tinkering so upgrading and tuning my car is an intriguing concept to me. I have the brains for it so now I just need a good start on where to attain the knowledge.

Looking for a few things:
More throttle response (New exhaust and a free flowing intake should help, but what else?)
More power.


I want it to sound good. Not that fart in a fishbowl $30 muffler good either. Now, where should I start? Anyone on here with the same vehicle? (2003 Chevrolet Cavalier LS Sport automatic coupe)

I also need a new driver's seat so new seats are in order.

So:
Intake
Exhaust
Cams?
Head porting maybe. Seems to be an easy addition of power as long as you can handle a dremel.

I'm looking to make my own intake and exhaust from this site. http://www.airflowonline.com/products.html

Thanks in advance.
