Street Slayer Carbon Fiber Slip-On Exhaust

The M4 Exhaust Street Slayer is a carbon fiber slip-on exhaust system engineered for the Kawasaki ZX-6R models from 2009-2026. Constructed from carbon fiber, this slip-on system replaces the stock exhaust valve and muffler box, offering a more aggressive tone and improved flow. Importantly, it retains the factory catalytic converter, ensuring compliance with emissions standards where applicable. The exhaust comes equipped with a removable Stage 1 quiet insert (Q5) for customizable sound levels. A Stage 2 quiet insert (Q4) is available separately. Note: This exhaust is intended for US models only. It does not include the necessary O2 fitting for the second O2 sensor found on European models.
