Yoshimura RS-9 Dual Exhaust System Honda CRF450R

Introducing the Yoshimura RS-9 Exhaust System. The modern dual-muffler configuration gave Yoshimura the opportunity to create an entirely state-of-the-art muffler built specifically for the dual-muffler dirt bikes. They have worked with Top AMA Pro Riders to achieve maximum performance and mass centralization, and to optimize rider usability. The RS-9 Exhaust features uniquely sculpted Carbon Fiber end-caps with a Tunable Insert System, so you can fine-tune power delivery and decibel levels to your specifications.


  • Parallelogram-shaped muffler
  • Increased muffler volume over stock system, resulting in better throttle response and noise cancellation
  • Light-weight muffler construction with carbon fiber end-cap
  • CNC machined muffler bracket
  • Reduced weight over OEM system
  • Vertical tail-pipe divider splits exhaust gases more evenly for improved mid-top power and throttle response
  • Yoshimura Signature Series muffler
  • Titanium header
  • Optional AMA Pro Sound Inserts are available separately
  • 100% Made in the USA
