Yoshimura RS-9T Exhaust System Honda CRF450R / R-S / RX 2017-2022

Yoshimura RS-9T Exhaust System Honda CRF450R / CRF450RX / CRF450R-S Yoshimura has been working tirelessly on the development of the RS-9T (Tapered) Exhaust with American Honda HRC’s engineers to achieve maximum performance and mass centralization, to optimize rider usability. Yoshimura achieved their goal by moving the RS-9T mufflers forward and relocating them under the side number plates. Working with Honda R&D in Japan and the HRC Japan MX Race Team, Yoshimura was able to deliver an exhaust that provides more tractable power with improved torque which in turn leads to better handling and performance. Features: 3-stage header provides broader power range and improves throttle response Tail pipe divider creates smoother exhaust flow and better velocity to the right and left tail pipe Compact forward positioned RS-9T dual muffler design provides lower center of gravity for better mass centralization Larger RS-9T core creates improved throttle response, and stronger mid to top end power RS-9T mufflers have more volume than stock to provide a decrease in overall dB noise level Works with or without Honda’s optional electric start system 100% Made in the USA
