Product Description


Yoshimura RS-9 Signature Series Slip-On Exhaust

Yoshimura Signature Series exhaust components are the answer for riders faced with ever-tightening noise and emissions regulations at the federal level. All Signature Series components are independently tested, documented, and marked as required by state and federal regulations as CARB/EPA-compliant.

Yoshimura's RS-9 slip-on muffler uses the same technology that goes into their top-of-the-line motocross systems. Premium packing material is used to meet noise requirements, while maintaining maximum performance. The parallelogram-shaped exhaust sleeve increases internal muffler volume which produces better noise cancellation and improved throttle response.

  • 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
  • Includes all required hardware and installation instructions
  • Significantly lighter than the OEM exhaust system
  • 80dB EPA noise emissions compliant
