best head pipe

[SLSD400exGUY]

what would be the best head pipe for a 05 400ex???

i have a hmf slip on should i go with the hmf head or something else.

i was told from a different thread that there is a head pipe thats bigger then stock and is the way to go.

any ideas???

wtf?

anyways, the fmf powerbomb header is a good way to go. but if is stock besides the pipe and filter, you might be losing a little low-end if you swap headpipes.
