Hi, need a bit of help. I've got a e-ton viper 90cc quad that I've give to my little sister, she was out riding it and the exhaust has snapped off next to the flange where it bolts to the engine, I've looked about for a new exhaust but can't find one, what other 90cc quad exhausts fit the Eton viper 90, I'm in the uk, thanks for reading and any help given
