what pipe is the loudest for the 400ex? i would have thought that it was the fmf but im not sure? how loud would it be in comparison to a stock raptor.

also what is the best pipe to improve bottom end and midrange power on a 400ex? any suggestions please.

HMF with quiet core..:macho

is that strictly low and midrange gains? or will there be some gain in top end?
