Product Description


Yoshimura RS-9 Race Series Full Exhaust System

If you're looking for that competitive edge, look no further than Yoshimura's Race Series exhausts. These exhaust components are designed with nothing but power in mind. Each Race Series system is developed in accordance with noise compliance regulations imposed by most race sanctioning bodies worldwide.

Initially developed specifically for the Honda Grom, Yoshimura took the opportunity to try out the RS-9 muffler profile and it's been proven to be the perfect choice. The parallelogram-shaped sleeve increases internal muffler volume which produces better noise cancellation and improved throttle response. The system not only compliments your bike's size and styling, it also significantly reduces exhaust weight.

  • Parallelogram-shaped muffler
  • Increased muffler volume over stock system, resulting in better throttle response and improved noise cancellation
  • Light-weight muffler construction with carbon fiber end-cap
  • CNC machined muffler bracket
  • CNC mandrel-bent polished 304L stainless steel header
  • Includes all required hardware and installation instructions
  • Significantly lighter than the OEM exhaust system
