Yoshimura 99.06 in RS-12 244720S320 Header/Canister/End Cap Exhaust System

After over three years in development and testing we are pleased to announce the RS-12 is here! With the help of incredibly talented factory sponsored athletes, technicians, devoted engineers and a will to raise the bar, our RS-12 has now arrived. We considered all the details when it came to the RS-12. One look and you can see it's like nothing else on the market. As you get closer you will notice the details in every place on our new dirt bike system, from the matte carbon fiber end cap with decal inlays to the precise machined joints, this system is next level.

The Yoshimura RS-12 exhaust system, model 244720S320, combines an aggressive asymmetrical muffler profile with a matte carbon fiber end cap and precision-machined joints. Developed and tested over more than three years with factory-sponsored athletes, technicians, and engineers, the RS-12 is designed to maximize muffler volume, manage sound, add power, and provide increased clearance for the tire and brake caliper.

The system features a tapered muffler body inlet design and Yoshimura’s patent-pending Precision Taper Fit (PTF) insert ring. Its works-look matte carbon fiber end cap includes detailed decal inlays, while the carbon fiber cap design is intended to ease servicing compared with commonly used sandwich mounting designs.
