The SC-Project S1 exhaust is a tapered exhaust with a large outlet diameter for enhanced exhaust airflow. The S1 performance is based on technology directly developed in World Superbike racing.

Note: ECU remapping is recommended with this full system to achieve the best performance.

Note: For optimal performance, we highly recommend purchasing the SC-Project ECR (Electronic Catalytic Remover) along with this kit. Removing the catalytic converter may cause the RS 457 ECU to generate an error. Designed by SC-Project, the ECR ensures proper management of the catalytic converter removal. It is incredibly easy to install—simply connect it to the OBD socket, and it will automatically resolve the error, safely restoring the on-board electronic system’s functionality.
