hey guys what's the typical hp gains with a H/I/E setup when it's all said and done...specifically i'm thinking of a megan header, aem CAI, and an Apexi ws2 exhaust because that's what i'm planning on doing...already have the intake but gonna be getting the rest in about a month...anyone have any data on hp gains for the 3?

 

id say around 15, depending on your year, the older your car gets the less horsepower you got due to normal wear and tear. But yea, id say around 15 because you got name brand stuff

 

There might be close to 3 billion threads on this. Maybe a search with reveal some answers?

 

Seriously... LOCKED
