Unleash the raw power and aggressive sound of your 2017 and newer Kawasaki Ninja 650 or Z650 with the Austin Racing GP1R De-Cat Race Exhaust System. This high-performance, de-cat system is engineered for maximum exhaust flow, significantly boosting your motorcycle's performance.

The GP1R features a 60mm bore tip and is available in either sleek black or pure titanium. This system removes the catalytic converter for unrestricted exhaust flow and a noticeable increase in power and a more visceral exhaust note. While no remap is strictly required for operation, Austin Racing recommends a Power Commander V (PCV) or equivalent with a custom map to realize the full potential of this system.   

Please note: Installation of this system requires cutting your standard exhaust. Refer to the fitting instructions for detailed information.
