I read that the 06 450R HRC kit comes with a different headpipe, I have an 04 450R with an HMF slipon. I was wondering if anybody know whether the new Headpipe would fit mine or not. If not what would a good head pipe be.

 

i dont' think it will. for one, the new hrc kit is not even out yet. also, i believe the 06 exhaust port comes out of the head at a different angle or location. time will tell though...
