I just got a cav 00 and I'm looking for parts to get more horsepower want to buy exhsuast system and intahke and headers if you have any info let me know.

 

Biggest bang for you buck is an intake. I first bought a K&N, but it turns out autozone ordered me the wrong part, so instead I ordered from http://speedyperformanceparts.com paid $88 and it looks and sounds great, and recieved it in about 3 days. as far as exhaust goes your looking at a few hundred atleast, unless you just replace the muffler itself, in which case you wont have the full performance gain of replacing the whole exhaust. I have a 2001 2.2 and i think next step for me is intake manifold.

 

I have a 2.2 Cavalier with full stainless steelobx exhaust system, headers to muffler. I also have a a.e.m cold air intake that wraps around the engine right to the wheel well to get the coldest air. Then the last thing is a performance chip built into my air intake wires. For all this I payed about$350.
