At DMG Motorsports, we present the Yoshimura AT2 Street SO SS/SS/CF WF Works Yamaha slip-on exhaust (13320BP523) — a race-bred upgrade engineered specifically for the Yamaha YZF-R3 and MT-03 platform. Born from Yoshimura's Research & Development program, this AT2 (Alpha Taper 2) muffler pairs a stainless steel body with a bold matte carbon fiber end cap and faceted tip, delivering the aggressive look and unmistakable Yoshimura tone riders expect while adding genuine, measurable performance gains. As a Street Series slip-on, it bolts directly onto the stock header without disturbing the bike's emissions control system, making it a straightforward, street-legal way to sharpen your R3 or MT-03's character.

Features:

• Stainless steel muffler construction with Yoshimura's exclusive Works Finish for a durable, satin heat-toned appearance
• Matte carbon fiber end cap paired with an all-new faceted end cap design
• Custom matte carbon fiber heel guard specific to the R3/MT-03 application
• Delivers up to a 4.3% max horsepower gain and 3.8% max torque increase
• Sheds approximately 1.7 lbs versus the stock exhaust for a lighter, quicker-revving parallel twin
• Bolt-on Street Series slip-on design that retains factory emissions equipment for easy installation
• Proudly designed, developed, and made in the USA
• Fits Yamaha YZF-R3 (2015-2024) and MT-03 (2020-2024)
