I own a 2012 WR450 and am in need of a slip on exhaust, 2012 models already have the megabomb header stock so i only need a slip on. Is there anyway of fitting a FMF Factory 4.1 RCT Slip-On on a wr450? if not i will stick with the fmf powercore 4 but from my understanding the factory 4.1 is better?
this on fits yz450 and im not sure if they have the same dimensions as a wr,
im also getting the tuner so what map would be used for the factory 4.1?
thanks guys, and i apologise if this question has already been asked but i cant seem to find it!
