Yoshimura RS-9T Dual Full System - Honda CRF450R/CRF450RX 2017-2020

Upgrade your bike with the Yoshimura RS-9T Dual Full System. The RS-9T Dual was dyno and track tested by Honda R&D Japan, the American Honda MX Team and the HRC All Japan MX Racing Team. Its compact, forward-positioned dual muffler design lowers the center of gravity for better mass centralization, and the larger RS-9T core improves throttle response and power in the mid and top end.

This system features a stainless steel header and canisters with carbon fiber end caps, built to the same standards as Yoshimura's factory race exhausts. Yoshimura builds exhaust systems for factory race efforts, and the knowledge they gain on the track goes straight into their consumer products. That cycle of development is what makes the Yoshimura name synonymous with quality and performance, delivering more power, lower sound levels and better mass centralization. Every Yoshimura system is designed and dyno tested for the specific model it fits, so you get real gains you can feel, not just more noise.
