hey peeps, i have a 2003 pontiac sunfire(ecotec)and i have already put 21/4 5-zigen cat-back exaughst and a rk-sport cool air intake....anyways i was wondering what i should do next?

headers, free up the exhaust even more, get some more pipe and do a true cold air intake w/ the aem breather for those extra rainy days, larger plug wires and ngk iridium spark plugs...that should kick you a few extra ponies, if all done id say about +20 or 30hp is possible...thats just for starters anyway...later on you may wanna check out www.exploitedracing.com if you wanna boost your fire, they have excellent prices on t3/t4 turbo kits. but you can do what you want...your car...just tossing ya a few ideas.
