Yoshimura RS-9E Dual Exhaust System Honda CRF250R

The Yoshimura RS-9E racing system is designed to meet stringent FIM sound restriction standards while still maximizing power output across the entire power band. Additionally, the RS9E is developed for improved durability between service intervals due to a unique internal configuration. The RS9-E has been race tested and proven from the sands of Lommel, Belgium to the factory Supercross tracks in Southern California.

Features:

• Unique internal muffler configuration enables system to meet FIM noise regulations
• Longer durability between service cycles
• Parallelogram-shaped mufflers
• Aluminum canister with carbon fiber end-caps
• CNC machined muffler brackets
• Stainless steel header and tail-pipe
• Increased muffler volume over stock system, resulting in better throttle response and improved noise cancellation
• 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
