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???

 

Its a mater of what other parts you have to compliment the part your adding.



I've loked at many an article where diff cams, headers or exhaust has made cars lose horsepower.


So basicly the 10-15 hp for a header..........5-10 hp for exhaust is a general statement made by manufacturers.


It all depends what combination you got going. and some good dyno time to really find out what different parts are doing as far as horespower.

 

Honestly, with that combo, you probably gained 10-15 horse at most. And you probably spent $1000 for all that.

 

take it to the dragstrip and find out
