Anyone put an aftermarket pipe on a 02 or 03 YZ250?

[QUOTE="Sage, post: 477719, member: 22484"] just did 2 02 yz's 1 with a sst, stock silencer and v force reeds. it went from 41 to 46 1 with a pc, stock silencer, v force reeds, porting & a head mod it went from 41 to 53.3 After some parts swaping the end results were this - stock engine likes the sst better than the pc, a cleaned up cylinder with a little off the head likes the pc by 1.3 hp, they both take to the v force well and we saw no gains with the sst or 304 silencer over stock. 188 dyno runs later we have a 53.3 hp pump gas 02 YZ250, Nutec run coming soon. Hope this helps [/QUOTE]
