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 Series Exhaust System is designed for select Husqvarna and KTM dirt bikes. This system features an aggressive, asymmetrical RS-12 muffler profile that maximizes muffler volume, manages sound, adds power, and provides increased clearance for the tire and brake caliper. Its tapered muffler body inlet design and precision-machined joints contribute to the system’s detailed construction.

The system includes a works-look matte carbon fiber end cap with intricate decal inlays. The carbon fiber cap is designed to ease servicing compared with sandwich mounting designs commonly found in the industry. It also uses a patent-pending Precision Taper Fit (PTF) insert ring.
