Carbon fibre, titanium and TIG-welded bracketry combine to deliver a road-legal (EURO 4) exhaust that is as refined in its construction as it is relentless on circuit.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAsymmetric diamond-section canister optimises aerodynamics and gives the R6 an unmistakably aggressive racing silhouette.\u003c\/li\u003e\n\u003cli\u003eMatte carbon fibre end-cap minimises weight at the tail and offers outstanding heat resistance under sustained high-revving use.\u003c\/li\u003e\n\u003cli\u003eCNC-machined titanium coupling bushes guarantee micron-level precision fitment and perfectly aligned exhaust flow.\u003c\/li\u003e\n\u003cli\u003eTIG-welded titanium brackets provide exceptional structural rigidity while maintaining the clean, uncluttered aesthetic SC-Project is renowned for.\u003c\/li\u003e\n\u003cli\u003eIntegrated carbon fibre heat shield manages thermal output effectively, protecting surrounding bodywork and rider.\u003c\/li\u003e\n\u003cli\u003eRemovable dB-killer gives you two characters in one silencer: road-compliant sport note with the insert fitted, full-spectrum MotoGP roar without it.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality and Premium Materials\u003c\/h2\u003e\u003cp\u003eWhat separates the SC1-R from catalogue exhausts is the uncompromising selection of materials. The main canister shell is formed from ultra-lightweight carbon fibre, keeping unsprung and overall mass to an absolute minimum without sacrificing stiffness or longevity. The coupling bushes are individually CNC-machined from titanium billet, ensuring every unit leaves the SC-Project facility in Padova meeting the same exacting tolerances demanded by factory Superbike teams. TIG welding — the same process used for aerospace-grade joints — is applied throughout the bracket assembly, producing smooth, pore-free beads that resist vibration fatigue across thousands of kilometres.\u003c\/p\u003e\u003cp\u003eThe matte carbon fibre end-cap is not a cosmetic afterthought; it serves a genuine thermal management role, channelling exhaust gases away from heat-sensitive components and contributing to the silencer's remarkably low mass. Together, these choices reflect an exhaust engineered from first principles rather than adapted from a road-bike catalogue.\u003c\/p\u003e\u003ch2\u003ePerformance Gains\u003c\/h2\u003e\u003cp\u003eThe SC1-R is not purely a styling exercise. Fitted to the Yamaha YZF-R6 RJ27, the optimised exhaust routing and reduced back-pressure translate into measurable gains at the wheel: +2.8 PS at 14,200 rpm for sharper top-end acceleration and increased top speed, and +1.5 Nm of torque at 12,000 rpm for improved throttle response and mid-range pull out of slower corners. The reduction in system mass improves the R6's agility and changes-of-direction feel in a way no power figure alone can convey.\u003c\/p\u003e\u003ch2\u003eSound Character\u003c\/h2\u003e\u003cp\u003eWith the dB-killer installed the SC1-R produces a deep, sporting exhaust note that is entirely appropriate for road use and comfortably within EURO 4 limits. Remove the insert and the silencer delivers the full, unrestrained sound spectrum associated with SC-Project's MotoGP-derived canisters — a genuine racing soundtrack suited to track days and closed circuits. Two exhaust characters, one installation.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis silencer is a direct slip-on replacement for the Yamaha YZF-R6 RJ27, covering model years 2017 through 2026.
