Note: This exhaust system features an Electronic Catalytic Remover (ECR), specifically designed to address the issues caused by removing the stock catalytic converter on the new RS 457. Without this device, the removal can result in a persistent error that may lead to various riding problems. Developed by SC-Project, the ECR ensures proper management of the catalytic converter removal. Installation is straightforward—simply connect it to the OBD socket, and it will automatically handle the error, safely restoring the onboard electronic system's functionality.
