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.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDramatic 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)\u003c\/li\u003e\n\u003cli\u003eHydroformed carbon end-cap engineered for optimised aerodynamics and heat resistance\u003c\/li\u003e\n\u003cli\u003eAsymmetric diamond-shaped silencer body — distinctive racing profile that sets the R1 apart at a glance\u003c\/li\u003e\n\u003cli\u003eCNC-machined titanium sleeve inserts for precise fitment and optimised exhaust flow\u003c\/li\u003e\n\u003cli\u003eTitanium catalyst replacement pipe removes the OEM catalyst for improved gas flow and torque delivery\u003c\/li\u003e\n\u003cli\u003eCarbon fibre heat shield included for superior thermal insulation and a refined finish\u003c\/li\u003e\n\u003cli\u003eOptional dB killer included, giving adjustable volume for track noise regulations or quieter days\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePerformance and Sound\u003c\/h2\u003e\u003cp\u003eSC-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.\u003c\/p\u003e\u003ch3\u003eSound Levels at 6,500 rpm\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eVersion\u003c\/th\u003e\n\u003cth\u003eWith dB Killer\u003c\/th\u003e\n\u003cth\u003eWithout dB Killer\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e250 mm\u003c\/td\u003e\n\u003ctd\u003e108 dB\u003c\/td\u003e\n\u003ctd\u003e115 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e350 mm\u003c\/td\u003e\n\u003ctd\u003e107 dB\u003c\/td\u003e\n\u003ctd\u003e110 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003eThe dB killer threads in and out in minutes, making it straightforward to comply with circuit noise limits on trackdays without permanently compromising performance.\u003c\/p\u003e\u003ch2\u003eMaterials and Construction\u003c\/h2\u003e\u003cp\u003eTwo 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.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis slip-on system and catalyst replacement pipe are designed specifically for the following models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYamaha YZF-R1 RN32 (2015-2016)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R1M RN32 (2015-2016)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe single-seat exhaust bracket included in the kit ensures a secure, rattle-free mount.
