Yoshimura Honda CRF250R 14-17 Full RS-9 Dual Exhaust System

Introducing the all-new RS-9 Dual. The CRF’s new dual-muffler configuration gave us the opportunity to create an entirely new muffler built specifically for the dual-muffler CRFs. We worked with Top AMA Pro Riders to achieve maximum performance and mass centralization, and to optimize rider usability. We achieved all this while maintaining AMA Regulation sound levels. The RS-9’s uniquely sculpted Carbon Fiber end-caps feature a Tunable Insert System, so you can fine-tune power delivery and decibel levels to your specifications.

The RS-9’s parallelogram-shaped muffler body increases muffler volume over the stock system, which results in better throttle response and improved sound quality. The dual setup also allowed Yoshimura to position the mufflers closer to the bike’s center of gravity, which results in better handling.

Full System includes Dual RS-9 mufflers, stainless steel header and tail-pipe, installation hardware and detailed instructions.

Features:

• 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
• Reduced weight over OEM system
• Vertical tail-pipe divider splits the exhaust gases more evenly, for smoother flow, which improves mid-top power and throttle response
• Stainless steel header and tail-pipe
