How much Bolt Ons really add..
Its really funny how many different answers i get for how much HP Bolt ons will add. Ive ppl telling me an exhaust wil add 2 hp, to people that rave it wil add like 12........
With the bolt ons on my 4cyl 02 accord, (AEM CAI,Greddy Evo exhaust,Dc Headers, Aem Pulley) What's the realistic gain???
