DescriptionThe whole story▼
Machined from race-proven titanium and aerospace-grade carbon fibre, the SC-Project SC1-R Slip-On with catalyst replacement pipe represents the pinnacle of WSBK-derived exhaust engineering for the Kawasaki Ninja ZX-10 R and ZX-10 RR (2021-2026). Every component — from the hydroformed carbon end-cap to the CNC-machined titanium bushings — is built to the exacting tolerances demanded by World Superbike Championship competition, delivering a 5 kg weight saving alongside measurably sharper throttle response.
Key Features
- Hydroformed carbon end-cap engineered for aerodynamic efficiency and extreme heat resistance
- Diamond-section silencer body with an unmistakably aggressive racing profile derived directly from WSBK development
- Titanium connecting pipe replaces the catalyst for unrestricted exhaust flow and maximum power delivery
- CNC-machined titanium bushings guarantee a precise, rattle-free fit every time
- Carbon heat shield included for superior thermal management and a clean, professional finish
- Weight reduction of 5 kg versus stock (SC1-R: 2.5 kg vs. OEM: 7.5 kg) for sharper acceleration and improved chassis balance
Construction and Materials
SC-Project's commitment to material quality is immediately apparent when you pick up the SC1-R. The silencer body is constructed from high-grade carbon fibre, keeping mass to an absolute minimum while retaining structural rigidity under sustained high-rpm running. The hydroformed carbon end-cap — a process borrowed from aerospace manufacturing — produces a compound-curved surface that channels exhaust gases efficiently and resists heat fatigue far longer than conventional pressed steel or aluminium alternatives.
Titanium is used throughout the connecting hardware and pipe fittings. CNC machining ensures each bushing meets tight dimensional tolerances, eliminating the fitment slop that can cause vibration and premature wear. The titanium construction also reduces heat transfer to surrounding bodywork, keeping the chassis area clean and the rider's leg away from excessive radiated warmth during track sessions.
Performance and Sound
Optimised internal geometry improves exhaust scavenging across the rev range, translating directly into sharper throttle response and improved torque delivery out of slow corners — exactly where lap times are won on the ZX-10 R. The SC1-R produces a purposeful, deep racing exhaust note shaped by SC-Project's specialist acoustic engineering.
Sound levels measured at 7,000 rpm:
- With dB killer fitted: 106 dB — strong, characterful and broadly suitable for track-day noise limits
- Without dB killer: 113 dB — full, uncompromised racing sound
This system is developed exclusively for racing use and is not homologated for road use.
