The canister body is fabricated from aerospace-grade titanium, joined throughout by hand-finished T.I.G. welds that ensure structural integrity under sustained high-rpm use. CNC-machined titanium collars guarantee a precise slip-on fit with zero play, while heat-resistant acoustic insulation maintains consistent sound character across all operating temperatures. The carbon fibre twill end cap — a hallmark of SC-Project's top-tier range — adds visual drama and genuine thermal performance in equal measure. The black metal outlet element completes the look with a seamless, purposeful finish.\u003c\/p\u003e\u003ch2\u003ePerformance on Road and Track\u003c\/h2\u003e\u003cp\u003eThe SC1-S is engineered to liberate measurable gains over the stock exhaust system. Dyno testing on the Yamaha YZF-R1\/M RN49 demonstrates an increase of +1.5 hp at 12,000 rpm and +1.0 Nm of torque at 12,100 rpm, delivered through an optimised exhaust flow path that improves gas scavenging and throttle response across the rev range. The titanium link pipe is shaped to maintain ideal back-pressure characteristics, keeping power delivery smooth and linear whether you are navigating road traffic or chasing lap times. Because no ECU recalibration is needed, the transition from factory exhaust to SC1-S is genuinely straightforward.\u003c\/p\u003e\u003ch2\u003eSound Character\u003c\/h2\u003e\u003cp\u003eThe SC1-S is celebrated for a deep, dark, resonant exhaust note that amplifies the crossplane character of the R1 engine without becoming antisocial on the road. A purpose-designed dB killer and block system are included as standard, maintaining legal compliance while preserving the throaty, layered acoustic profile that distinguishes an SC-Project exhaust from any aftermarket alternative. Remove the dB killer for track days and the SC1-S reveals the full-throated voice it inherited from its SC1-R lineage.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe SC-Project SC1-S Y11B-T124 is designed and approved for the following motorcycles:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYamaha YZF-R1 RN49 (2017, 2018, 2019)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R1M RN49 (2017, 2018, 2019)\u003c\/li\u003e\n\u003cli\u003eAll EURO 4 variants of the above models\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe titanium link pipe mates directly with the original catalytic converter, retaining the standard mid-pipe and collector.
