Hey i was just curious if anyone knows how many HP you can gain from a set of headers and a cat back exhaust? i was going to turbo my 2.2 but i don't want to blow my motor because it is still pretty new so? does annyone know what kind of reflashes they make for a 2.2 non ecotec. Thanks guys let me know. One other thing, what is the fastest 2.2 naturally asparated non ecotec? Thanks again
513.2796142 hp gain from header (no s, yo only have one) and 2 from a catback. honestly man, everybody's car is different, and so is every exhaust system. no two cars are going to gain the same amount.

Gains from bolt on's are all basically negligible. It could be 2whp or 10whp. It is real expensive to go N/A and get big gains.Don't expect a lot of hp out of your 2200 without some boost or nitrous.
