Yoshimura Exhaust RS-9 Stainless Full System (Honda Grom)

Description: 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 a perfect choice. The Parallelogram-shaped sleeve increases internal muffler volume, resulting in better noise cancellation and improved throttle response. Our system not only compliments the Grom's size and styling, it also significantly reduces weight.

NOTE: This Yoshimura exhaust system is designed and intended for closed course competition use only. Also, available Yoshimura Exhaust RS-9 Carbon Full System (Part# 121200H220). Downloadable Instructions & Parts Diagram.
