Description

The M4 YA-CEKR115 is a black stainless steel catalytic converter eliminator pipe engineered for the Yamaha YZF-R1 and R1M models. This component is crafted from durable stainless steel and finished with a high-temperature ceramic coating for longevity and aesthetics. It includes an O2 sensor bung, allowing for seamless integration with your motorcycle's existing or modified exhaust system. Depending on the specific configuration, it can remove approximately 11 to 13 pounds from the stock system. It's important to note that all M4 exhaust systems are designed and intended for closed-course competition use only. This product is specifically designed for the Yamaha YZF-R1, covering model years from 2015 through the latest available, with some sources indicating fitment up to 2026.
