Complete system including the gasket, clamp, carbon heat shield etc ready to bolt on.

The completely reworked alluminium silencer for 2020, that looks just like the works ones and is the bigger diameter bore all the way through.

Header is the big bore as standard on the 300rr & 301rr.

This will fit all models of 4rt and is a great upgrade for the 300 or the 260 at a much more sensible cost than an aftermarket system.

Option for silencer only too.
