hp difference between long and short headers
we all know headers give at laeast a 15 hp gain over manifolds, but does anyone know the exact gain form short tubes to long tubes, perhaps dyno test. are long tubes that much surperior then shortys, overcoming the much more extreme intallation and ground clearence problems, or is just a 5 hp gain over shortys?
I know it varys from header to header, i have hookers in my mind

long tubes help out with low and mid range power (if i remember right) better than shortys but other than that I'm not sure of the differences, I'm putting them on the 355
