Header... Cat back... High flow cat??
Considering dropping about $100-$150 on one of the above. Just wondering what people have found as an average HP gain when adding the above mentioned to a civic. Want to get the best HP for the cash. I want that exhaust sound and that's why I want to use the $150 towards that instead of other HP adder type mods.
