The RS9 Parallelogram shape increases internal muffler volume resulting in better noise cancellation and improved throttle response. Along with the sculpted carbon fibre end-cap there is significant weight reduction important for smaller machines.
The mufflers are also fitted with a CNC machined bracket for extra strength. Developed to fit without fuel modification. All parts required for fitment are included (brackets/fittings/link pipe etc.) with full fitting instructions.
