Introducing our latest muffler design, AT2 for the bike that has won many superbike championships and has a special place in the heart of Yoshimura.

Our AT2 slip-on for the GSX-R1000 makes the high revving inline-four come to life and sound like it should. Features include our exclusive Works Finish, an aggressively styled matte finish heal guard and end cap complimented by a facet-formed tip. End result in 2.2% max power increase, 2.1 lbs. weight saving and being a Street Series slip-on makes it 50-state emissions legal.

New Yoshimura Works Finish takes on a unique colouring after it goes through a heat cycle on the motorcycle that looks much like the titanium works components our factory racers use.

• Contemporary Satin/matte finish
• Uniform heat colouration
• Increased fatigue strength
• Increased scratch and stain resistance
