Yoshimura RS-9 Exhaust System

The Yoshimura RS-9 full exhaust system is the result of working with top AMA Pro riders to achieve mass centralization, maximum performance, and to optimize rider usability. The vertical pipe divider on the Yoshimura RS-9 exhaust splits exhaust gases more evenly over the stock system, resulting in power gains in the mid to top end RPM range of dual muffler bikes. The uniquely sculpted Carbon Fiber end-caps feature a Tunable Insert System, this allows for fine-tuning of decibel levels and power delivery based on personal preference.

Nearly all Yoshimura exhaust systems that have won Motocross or Supercross championships are members of the Yoshimura Signature Series. All Signature Series pipes have been tested, documented, and marked as required by federal and state regulations. Working in conjunction with factory race teams has allowed Yoshimura to increase performance, keep sound levels to a minimum and centralize mass. The end result is a exhaust system that gives you an unparalleled competitive advantage.
