YOSHIMURA RS-9 FULL SYSTEM EXHAUST 14-17 CRF250R RS9-COMP FS SS/AL/CF-TIP*2

All Signature series exhaust are tested, documented and marked with appropriate EPA noise emissions labels

Dual-muffler design exhaust system

Achieves maximum performance, mass centralization, and rider usability

Systems feature three-stage tapered headpipe for the best power gains, better throttle response and power delivery

Vertical divider splits the exhaust gases more evenly for smoother flow to the mufflers for better mid-top power and throttle response

Parallelogram-shaped muffler bodies increase muffler volume over the stock system for even crisper throttle response and reduced noise levels

Systems meet AMA noise sound regulations right out of the box (AMA 2-Meter Max and Amateur 94 dB sound compliant)

Muffler inserts are tunable to adjust power delivery and noise levels

Stainless Steel Header / Aluminum Mufflers / Carbon Fiber End Caps

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.

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
• Series: Signature
• Muffler Type: RS-9 Dual
• Header/Muffler/End Cap TYPE: SS/AL/CF

Optional AMA Pro Sound Inserts are available separately.
