SC-Project SC1-R Slip-On Silencer + Catalyst Replacement Pipe Yamaha YZF-R1/M RN32 (2015-2016)

A track-focused exhaust upgrade that also transforms everyday riding: the SC-Project SC1-R slip-on paired with a titanium catalyst replacement pipe gives your Yamaha YZF-R1 or R1M (RN32, 2015-2016) a genuine weight saving of up to 5 kg over stock, sharper throttle response, and a race-bred exhaust note — all in a package that bolts on without specialist tooling. Whether you use the bike primarily on road days and the occasional circuit, or you are chasing lap times full-time, this kit delivers meaningful, tangible improvements from the moment you ride.

Key Features

• Dramatic weight reduction: 250 mm version weighs just 3.0 kg versus the 8.0 kg stock system (saving 5 kg); 350 mm version weighs 3.5 kg (saving 4.5 kg)
• Hydroformed carbon end-cap engineered for optimised aerodynamics and heat resistance
• Asymmetric diamond-shaped silencer body — distinctive racing profile that sets the R1 apart at a glance
• CNC-machined titanium sleeve inserts for precise fitment and optimised exhaust flow
• Titanium catalyst replacement pipe removes the OEM catalyst for improved gas flow and torque delivery
• Carbon fibre heat shield included for superior thermal insulation and a refined finish
• Optional dB killer included, giving adjustable volume for track noise regulations or quieter days

Performance and Sound

SC-Project developed the SC1-R directly from their involvement in international racing series, and the results show in real-world performance. Removing the stock catalyst with the included titanium connection pipe opens up the exhaust path, improving throttle response and torque delivery across the rev range. The high-temperature sound-absorbing material inside the silencer produces a deep, authoritative exhaust note without the thin, harsh character of lesser aftermarket cans.

Sound Levels at 6,500 rpm

The dB killer threads in and out in minutes, making it straightforward to comply with circuit noise limits on trackdays without permanently compromising performance.

Materials and Construction

Two finish options are available, each suited to a slightly different priority. The titanium version (Y11A-DET90T / Y11A-DET93T) prioritises absolute minimum weight and exceptional corrosion resistance, making it the natural choice for dedicated track machines. The carbon version (Y11A-DET90C / Y11A-DET93C) combines a woven carbon fibre outer with equally aggressive weight savings and outstanding heat tolerance, giving street-legal track bikes a visual statement that is hard to ignore. Both versions share the same hydroformed carbon end-cap, CNC-machined titanium sleeve inserts, and included carbon fibre heat shield — there is no compromise on build quality between them.

Fitment and Compatibility

This slip-on system and catalyst replacement pipe are designed specifically for the following models:

• Yamaha YZF-R1 RN32 (2015-2016)
• Yamaha YZF-R1M RN32 (2015-2016)

The single-seat exhaust bracket included in the kit ensures a secure, rattle-free mount. All mounting springs and bolts are provided for a straightforward installation.

Important Notice

This exhaust system is developed for racing use only and is not approved for use on public roads. It does not carry road-legal homologation. Use is restricted to closed circuits and private off-road environments.
