Yoshimura Exhaust RS-9 Carbon 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 Grom's size and styling but it also significantly reduces weight.
When changing a cylinder kit or an exhaust, it's a good idea to pick up a few extra exhaust studs + nuts M8 set since these can easily need replacing and bring your project to a grinding halt while you wait.
