The area under the curve is what is most important you spend maybe a fraction of a second at th actually peak rPm so what you really feel is the overall gain and a much thickEr powerband. They even tested shortys vs long tubes and the bbk shortys had an average gaIn of 12-15 hp/tq but only a 5 peak gain on each. This tells us that headers may not increase you peak numbers all that much but make the overall power curve thicker and longer meaning you will make more power throught the rpm range and that's really where it counts.

besides, its not a Honda V-tec (not dissing) engine to be really worried about peak Hp actually I see those 2v's power band start dropping after 4.5k rpm.... so yeah, more power a cross the power band is nicer than only peak Hp

Car had a bbk O/R X and went to an O/R X with the long tubes
