Im buying a new yfz 450 at the end the febuary. I think im going to get the gytr's aluminum muffler and header pipe, i also think im getting there air filter and jet kit, i will take off my air box lid, how much better will these mods make the 450 run and how much horse will it add, also does the cam mod do alot and is it pretty easy
thanks
