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 Full Exhaust system for 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, to optimize 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 and performance.
