Yoshimura R&D of America’s RS-9 Full System was engineered to reduce weight, making it a perfect fit for smaller vehicles.The Honda GROM has created quite a phenomenon in the motorcycle world and we’re right on top it. We took the opportunity to try our new RS-9 muffler profile and it’s been proven to be the perfect choice. The Parallelogram-shaped sleeve increases internal muffler volume, resulting in better noice cancellation and improved throttle response. Our system not only compliments the Grom’s size and styling, it also significantly reduces weight.
