Ok so im not too smart when it comes to cars. So i was wondering if i can get some advice on what i can do to basically make my car faster. I have a 02 camry LE (i think) and its a 4 cylinder. All my friends have told me to get intake, exhaust and all that good stuff but i really dont have a clue on what i should do

and my budget isnt too high : /

so please give me some advice on what i can do
