yz250f exhaust transplant...

well my buddy bent up his exhaust on his '04 yz450f pretty good

his lil brother has a yz250f with an aftermarket exhaust so he took the 250f stock exhaust and put it on the 450f

it is a lil shorter... looks a lil skinnier and i think sounds different..

just curious if this will cause any problems like excessive backpressure or if this is fine to run

thanks and any input is appreciated

probably if its a smaller pipe it will restrict it more than the regular pipe will causing a little loss in power.

and..... hey, you never got me any pics of your GN, you got any???
