Yoshimura RS-9 Exhaust System
Introducing the Yoshimura RS-9 Exhaust System. The modern muffler configuration gave Yoshimura the opportunity to create an entirely state-of-the-art muffler built specifically for 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.
