Hey guys just wanted to say you have an awesome site here. Anyways I just bought an 05 Sunfire-Automatic. I was wanting to get some input on some performance ideas that will really work. I want a True CAI and a cat-back and header. Let me know what works and what is just a waste of money.
Thanks,
Ryan
Aem makes a badass intake you can get for like 230 and cat back you can get a 2.5 inch with high flow muffler for about 230 on ebay and it sounds great, and headers you can get either rksport which are way overpriced and ive heard that they warp hardcore. Pacesetter makes headers you can pick up for about 180 on ebay. That will open up the motor a bit but if your serious about getting some power here is a link you should try

I like that link! The RK header fits like...... on the 02.

I have bought almost all my engine and exhaust parts from RKSport. I have the 4.2.1 header along with the magnaflow high-flow cat and dual-exhaust, but the first thing I replaced was the spark plug boot wires. I noticed a pretty big difference with that alone. You could probably get away with using just the stock convertor though.
