The 2017 CRF450R's engine and muffler configuration gave us the opportunity to create an entirely new system built specifically for the CRF450 machines. Introducing the Signature Series RS-9T tapered dual muffler exhaust system for the CRF450R.

Yoshimura has been working tirelessly on development with American Honda HRC's engineers to achieve maximum performance and mass centralization, to optimize rider usability. Yoshimura achieved all this by moving the RS-9T mufflers forward in order to tuck in under the side number plates. Working with HRC race engineers and the 449cc Unicam engine and its unique downdraft fuel injection system, Yoshimura was able to deliver an exhaust that provides more tractable power and improved torque.

Features:

• Dyno and track tested by Honda R&D in Japan, American Honda MX Team, and HRC All Japan MX Racing Team
• 3-stage header provides broader overall range of power and throttle response
• New tail pipe divider creates smoother exhaust flow and better velocity to the right and left tail pipe
• New 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 power in mid and top end
• 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
