Show original supplier description

The SC-Project S1 Full System Exhaust is a premium performance upgrade designed for the Yamaha MT-09 and MT-09 SP models from 2021 onwards. It integrates seamlessly with original lambda probes. Drawing technology directly from World Superbike racing, the S1 exhaust utilizes a conical silencer body shape. This design is crucial for maintaining proper back pressure and ensuring optimal ground clearance during extreme lean angles, a critical factor for performance riding. SC-Project leverages its extensive experience from MotoGP, Moto3, Moto2, and Superbike racing to develop exhaust systems that push the limits of performance. The S1 exhaust embodies this racing heritage, offering a race-inspired design with aeronautical-grade materials. The system includes bike-specific mounting hardware for a straightforward installation and comes with a 24-month factory defect warranty.
