At DMG Motorsports, we present the Yoshimura Street AT2 Slip-On Exhaust SS/SS/CF (19450BP520) — a purpose-built stainless steel muffler engineered specifically for the CFMOTO 450SS and 450NK. This slip-on takes the platform's already impressive value and elevates it with a genuine performance and sound upgrade straight from Yoshimura's Chino, California R&D facility. This AT2 Street Series slip-on with carbon fiber heel guard is designed to optimize power, waking up the 449cc parallel twin so the bike sounds 200cc bigger than it actually is. Dyno testing confirms real seat-of-the-pants gains, with a 6.3% max horsepower increase and a whopping 10% max gain in torque, all at almost half the weight of the stock muffler. As a Street Series system, it's a slip-on/bolt-on application that does not require tampering with the vehicle's emissions control system, is CARB/EPA tail-pipe emissions compliant, and is marked with the appropriate EPA noise labels. Built with an aggressive new design and premium materials, this AT2 slip-on gives your 450SS or 450NK the look, sound, and power upgrade it deserves.
