exhaust?

[JDiablo]

i was lokin at the HMF site today and i was pist cause they dun make a complete system for a 300ex so i was wondering can you use a HMF slip-on and jus for example a white brothers head-pipe or some other headpipe?

you will be able to use any aftermarket headpipe that fits a slip-on silencer. but i don't know which ones they are for a 300ex. i know for a 400ex, the fmf powerbong can be used for all slip on silencers. the white brothers headers can't be used on slip on silencer for the 400ex though.
