With a combined system weight of just 1.75 kg — a saving of 6.25 kg over the stock exhaust — and a free-breathing Ø70 mm outlet, every throttle input is sharper, every lap faster.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDramatic 6.25 kg weight reduction (SC-Project system: 1.75 kg vs stock: 8 kg) for measurably improved acceleration and handling balance.\u003c\/li\u003e\n\u003cli\u003eTitanium de-cat link pipe optimises exhaust flow, eliminating back-pressure and unlocking the CR-T's full performance potential.\u003c\/li\u003e\n\u003cli\u003eLarge Ø70 mm outlet for maximum exhaust gas throughput and peak flow efficiency.\u003c\/li\u003e\n\u003cli\u003eT.I.G.-welded titanium and carbon components with CNC-machined titanium bushings for race-grade precision and long-term durability.\u003c\/li\u003e\n\u003cli\u003eTitanium flame-guard mesh for an unmistakable motorsport aesthetic and optimised exit flow.\u003c\/li\u003e\n\u003cli\u003eCompatible with original pillion footpegs and pre-drilled for the OEM lambda sensor connection.\u003c\/li\u003e\n\u003cli\u003eTwo finish options: Titanium (Y11B-DET36TR) and Carbon with rivet plaque (Y11B-DET36CR).\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTrack Performance\u003c\/h2\u003e\u003cp\u003eThe CR-T is SC-Project's most race-focused slip-on silencer, developed directly from their MotoGP programme. The titanium cat replacement pipe removes the catalytic converter entirely, allowing spent gases to exit through the shortest, smoothest possible path. The result is a throttle response that feels immediate and a power delivery that rewards precise corner exits. CNC-machined titanium bushings at every joint guarantee leak-free fitment under sustained high-temperature racing conditions, while T.I.G. welding throughout ensures the assembly remains rigid even under the vibration loads a pushed R1 generates at the limit.\u003c\/p\u003e\u003ch2\u003eMotoGP Sound\u003c\/h2\u003e\u003cp\u003eAt 123 dB measured at 6,500 rpm, the CR-T produces a raw, unfiltered racing note that is instantly recognisable on circuit. There is no dB killer supplied or intended — this system is engineered purely for track use where maximum sound presence is an asset, not a liability. The titanium flame-guard mesh at the exit contributes both to the aggressive visual signature and to controlled gas dispersion at high revs.\u003c\/p\u003e\u003ch2\u003eMaterials and Build Quality\u003c\/h2\u003e\u003cp\u003eSC-Project's material selection draws directly from MotoGP-level engineering. The titanium version (Y11B-DET36TR) prioritises absolute minimum weight combined with outstanding heat resistance and structural integrity. The carbon version (Y11B-DET36CR) pairs a hand-finished carbon fibre canister with a rivet plaque for a motorsport visual that complements the R1's aggressive bodywork. Both variants share the same titanium end cap, titanium cat replacement pipe and CNC-machined titanium bushings, so performance is identical regardless of the finish chosen.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eYamaha YZF-R1 RN49 — model years 2017, 2018, 2019\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R1M RN49 — model years 2017, 2018, 2019\u003c\/li\u003e\n\u003cli\u003eCompatible with original pillion footrest hangers\u003c\/li\u003e\n\u003cli\u003ePre-drilled for OEM lambda sensor — no additional adapter required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eImportant Notice\u003c\/h2\u003e\u003cp\u003eFOR RACING USE ONLY.
