what kinda of head pipes

[Skannes]

i want a new head pipe for my 400ex and i was wondering if i could mate other headers for a procircuit T-4 can i do that or not?
your response would really help me

[cals400ex]

the only two i know you can use with all slip on silencers is the pro circuit and the fmf powerbomb.

[Skannes]

do you no how power it will give me if i get the powerbomb with the T-4?

[cals400ex]

i have honestly never tried this setup. i know rico and others have the powerbomb header and really like it. i can't imagine it giving a ton of power but i bet it can't hurt either. i realize that didn't help much

yeah, i've always wondered if mixing the header and silencer(using two differ brands) would make a difference...
