Simple to install and a direct replacement. A trapezoidal under-seat muffler with a round exit carbon fibre end-cap and a straight baffle for ample flow allowing a large volume of packing material. It dramatically improves your bike's visual appearance.
Produces more power, more torque and saves weight. All parts required for fitment are included (brackets/fittings/link pipe etc.) with full fitting instructions. Developed to fit without fuel modification, and to give the unique Yoshimura racing sound.
