Stunning look, easy mount, low weight, more power, more torque. These are characters of the exhaust systems b Remus and Sebring. For your F650CS from 02 on we have the Remus GrandPrix. For the F650GS and Dakar from 04 on we have the slip on jet steram in high steel inclusive KAT. The muffler is easy to mount and compared to the original low in weight. But most important is the dull, sporty sound.
