I have a civic and i was wondering how much horsepower i would be able to get out if i got headers for my ride.?

 

3

 

With just headers, maybe 3 or 4HP.
With headers, high-flow cat, and a cat-back system, maybe 8HP.

 

double that since you have more than one headers.

 

lol,

u wont get too much man.......with exhaust, headeR and intake mite get u 10-12 HP........but thas it.,

 

look at it this way: HPs are based on percentages...not set numbers. a header will give you mabybe 3 or 4 % hp...so if ur runnin a stock 6gen EX u'll b runnin about 4 hp at the crank w/ a header. if your runnin a highly modded turbo B16 runnin at 400 hp...u'll gain ten for the header. these numbers arent acurate...but its to give you a general idea that its based on percentages.
