Its retro-inspired 70 mm outlet, T.I.G.-welded titanium joints and laser-etched SC-Project logo give the system a visual identity that is unmistakably race-bred — available in either natural carbon or raw titanium to suit the aesthetic of your build.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRetro-racing design with a large 70 mm outlet exit, available in carbon (Y11A-DET70C) or titanium (Y11A-DET70T) finish\u003c\/li\u003e\n\u003cli\u003eSaves 6.2 kg over the stock system (SC-Project system: 1.8 kg vs. OEM: 8.0 kg) for a dramatic improvement in handling agility\u003c\/li\u003e\n\u003cli\u003eTitanium cat-replacement connecting pipe removes the catalytic converter for unrestricted exhaust flow and maximum power delivery\u003c\/li\u003e\n\u003cli\u003eCNC-machined titanium sleeves ensure a precise, rattle-free fit on the Yamaha RN32 mid-pipe junction\u003c\/li\u003e\n\u003cli\u003eT.I.G.-welded titanium and carbon components deliver racing-grade structural integrity and heat resistance\u003c\/li\u003e\n\u003cli\u003eCompatible with the original pillion footrests — no fairing or rearset modifications required for fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eThe GP70-R carries SC-Project's long history of supplying exhaust systems directly to MotoGP and Superbike teams. The wide, circular outlet is a deliberate nod to the large-bore canisters seen in prototype racing during the early 2000s — a form that has since become synonymous with SC-Project's road-racing aesthetic. On the Yamaha YZF-R1\/M RN32, the canister sits flush with the tail unit, complementing the bike's angular bodywork whether in track livery or stripped naked.\u003c\/p\u003e\u003cp\u003eThe carbon version (Y11A-DET70C) pairs woven carbon-fibre construction with the aggressive lines of the R1\/M's tail, adding heat resistance and a visual contrast against the blue-and-white factory colour scheme. The titanium version (Y11A-DET70T) takes the opposite approach — a brushed, metallic finish that ages with character, growing lighter in colour with heat cycles in a way that is unique to each individual exhaust.\u003c\/p\u003e\u003ch2\u003ePerformance and Sound\u003c\/h2\u003e\u003cp\u003eWith the catalytic converter removed via the dedicated titanium connecting pipe, exhaust gas flow is no longer restricted, allowing the R1's 998 cc crossplane inline-four to breathe more freely across the rev range. Throttle response sharpens and mid-range torque delivery becomes more linear — exactly what is needed when chasing lap times.\u003c\/p\u003e\u003cp\u003eThe GP70-R produces 123 dB at 6,500 rpm. There is no db-killer fitted as standard; the system is engineered for pure racing use and is tuned to deliver the unfiltered, high-frequency howl that the crossplane engine is capable of producing. This is not a road-going compromise — it is a dedicated track system.\u003c\/p\u003e\u003ch2\u003eConstruction and Materials\u003c\/h2\u003e\u003cp\u003eEvery joint in the GP70-R system is T.I.G. welded by hand to meet SC-Project's exacting tolerances. The canister body — in either carbon or titanium — is shaped to manage heat while keeping mass to an absolute minimum. CNC-machined titanium sleeves at the connection points prevent micro-movement under repeated thermal cycling, which is a common failure point on lesser aftermarket systems. The laser-engraved SC-Project logo and included sticker kit complete the racing finish.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis slip-on silencer and cat replacement pipe combination is developed specifically for the following motorcycle:\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 system retains compatibility with the original pillion footrests.
