Hi
Ive got a zxr 400 race bike now running 72bhp but its got standard headers on it with a scorpion can fitted,i was wondering what sort of extra bhp i will get from changeing the headers,
cheers in advance

what mods have you done so far to get to 72bhp?

Thanks,
Roy

a good exhaust will allow the bike to hold onto its power at the topend, you might only get another 2bhp peak, but you might gain 1500rpm of that "peak"

beet, mhp, micron ... up to your wallet really innit..

i am thinking on buying a mhp exhaust system,do i go for the 32mm or the 35mm
