crf50 fmf exhaust used, works perfectly fine got a different style exhaust and have no need for this one anymore relatively clean hanger has some scuffing i had it on a xr70 and the mounting point didnt line up and thats the cause of that, does have a decent size dent on the bottom of the header doesn't effect anything but how it looks and its not visible on the bike, pipe sounded good just went a different route. thanks for looking
