Hi ..the united kingdom [uk] "fuel exhaust" are very good quality and have sold well in the uk transalp owners..the "roadlegal" has a removable baffle and is quieter than the FULL rave exhaust..the oval silencer is a better it than the round..also they do different lenghts..
they are a good company to deal with and answer emails easily...
The pro duro are very rare in Europe and are louder than the Fuel ..
The arrow are excellent too..and all the silencers route differently due to pipe bends..
