Yoshimura RS-12 Slip-On Exhaust – KTM & Husqvarna 250/350/450 (2023-2026)

The Yoshimura RS-12 Slip-On Exhaust for KTM and Husqvarna 250, 350, and 450 (2023–2026) delivers a proven performance upgrade developed over three years with input from factory-sponsored athletes, engineers, and technicians. The aggressive, asymmetrical RS-12 muffler profile maximizes volume, manages sound, adds power, and improves clearance for tires and brake calipers — purpose-built for off-road and motocross demands.

The matte carbon fiber end cap features intricate decal inlays and precision-machined joints, while the patent-pending Precision Taper Fit (PTF) insert ring ensures a secure, rattle-free fit. The tapered muffler body inlet promotes improved airflow and engine response. Servicing is simplified compared to traditional sandwich mounting designs.
