Yoshimura RS-9T Slip-On Exhaust Honda Grom
Yoshimura was very excited about the US release of the Grom back in 2013, and with the new refresh for the third gen Grom, Yoshimura’s R&D team anxiously waited to get their hands on one to develop this RS-9T Slip-On to the market. 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 which optimizes rider usability. Working with Honda R&D in Japan, Yoshimura was able to deliver an exhaust that provides more tractable power with improved torque which in turn leads to better handling.
Features:
- 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
- 100% Made in the USA
