is that the result after getting a CAI and a cat-back exhaust?? 10 or 15 HP from just headers! 4-2-1 setup? DC Sports? where did you get those astonomical numbers from just headers?!
dc sports claims its 4-2-1 headers for the accord produces 10-15 hp independently without any other mods. i cant actually say if its true or not but thats what they claim.
