Overview

The SC-Project S1 Full System Exhaust is a race-developed exhaust system for Yamaha motorcycles. Engineered with roots in MotoGP, Moto2, Moto3, and Superbike World Championship, it uses competition feedback to refine flow and durability.

This tapered, race-inspired exhaust is designed around World Superbike technology. Its large-diameter outlet enhances exhaust flow, while the conical silencer body helps maintain proper back pressure for responsive throttle feel. The conical profile also improves ground clearance for increased lean angles.
Show original supplier description
The SC-Project S1 Full System Exhaust is a premium, race-developed Italian exhaust system engineered for performance and style. This combination ensures strength, heat resistance, and a lightweight profile, with a significant weight reduction of -4.6Kg compared to the stock system (stock: 7.7 Kg, SC-Project: 3.1 Kg). The system provides a power increase of +2.8 hp at 9000 rpm and +2.8 Nm of torque at 5250 rpm. The S1's design incorporates a tapered, large-diameter outlet for improved exhaust airflow and a conical silencer body that helps maintain optimal back pressure. This design not only supports a crisp, performance-focused character and responsive throttle but also offers improved ground clearance for greater confidence during aggressive lean angles. This exhaust system is a "decat" system and comes with a removable dB-killer. Without the dB-killer, it produces 109 dB at 4375 rpm, and with it installed, it outputs 106 dB at 4375 rpm. It also includes provisions for a lambda probe. The S1 is designed for specific vehicle fitment, with bike-specific mounting hardware included for a correct and clean installation. It is handmade in Italy and comes with a 24-month factory defect warranty.
