Stainless/stainless/carbon fiber (Dual) header/muffler/end cap type. Full System. EMIS 3.

• 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
• Dyno and track tested by Honda R&D in Japan, American Honda MX Team, and HRC All Japan MX Racing Team
• 3-stage stainless steel header provides broader overall range of power and throttle response
• New stainless steel tail pipe divider creates smoother exhaust flow and better velocity to the right and left tail pipe
• Larger RS-9T core creates improved throttle response, and power in mid and top end
• New RS-9T mufflers have more volume than stock to provide a decrease in overall dB noise level
• Works with or without Honda's new optional electric start system
