not that i have a new bandit or anything, but most after market pipes are smaller then stock. the new 1250 pipe looks big, the yosh is most likely a 4" pipe. if the stock can is more like 6" then there might be more then enough room. when i had my 2000 1200 the holeshot pipe was way smaller then my stock can. i think it was more then a inch or two smaller. check what size the stock unit is, then see what the yosh is. if it is a inch or two smaller but bent a little higher it might be about as high as the stock can sits? just a thought?
