Every joint, every weld and every CNC-milled sleeve reflects a manufacturing standard drawn directly from SC-Project's MotoGP programme — delivered in a package that strips 6.2 kg from your machine's exhaust system alone.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDramatic 6.2 kg weight reduction over the stock system (SC-Project system: 1.8 kg vs. OEM: 8 kg), improving mass centralisation, turn-in and overall agility\u003c\/li\u003e\n\u003cli\u003eDe-cat titanium link pipe replaces the catalytic converter section for unrestricted exhaust flow and reduced heat soak into the airbox\u003c\/li\u003e\n\u003cli\u003eCNC-milled bushings and T.I.G.-welded titanium connections ensure a gas-tight, rattle-free fit under sustained track use\u003c\/li\u003e\n\u003cli\u003eØ70 mm outlet diameter — the same aggressive MotoGP silhouette that defines SC-Project's racing heritage\u003c\/li\u003e\n\u003cli\u003eTwo finish options: Titanium (Y11B-DET70T) with laser-engraved SC-Project logo, or Carbon (Y11B-DET70C) with riveted racing plaque\u003c\/li\u003e\n\u003cli\u003eCompatible with the original pillion footpegs and pre-drilled for the OEM lambda sensor connection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eConstruction and Material Quality\u003c\/h2\u003e\u003cp\u003eSC-Project's commitment to build quality is evident in every detail of the GP70-R. The titanium link pipe withstands the extreme thermal cycling of track sessions without distortion, while the CNC-machined sleeve interfaces guarantee a precise, leak-free slip-on fitment every time. T.I.G. welding — applied by hand — produces cleaner, stronger beads than automated MIG processes, and the result is an exhaust that looks as purposeful as it performs.\u003c\/p\u003e\u003cp\u003eThe titanium variant carries a laser-etched SC-Project logo that resists fading under heat, while the carbon version features a hand-riveted racing identification plaque that gives the can a distinctly pit-lane aesthetic. Both variants share the same internal construction and deliver identical acoustic and performance characteristics.\u003c\/p\u003e\u003ch2\u003ePerformance and Sound\u003c\/h2\u003e\u003cp\u003eRemoving 6.2 kg from a concentrated, high-mounted location lowers the centre of gravity and measurably reduces rotational inertia in direction changes. Paired with the de-cat link pipe's optimised exhaust gas routing, throttle response sharpens noticeably across the mid-range — precisely the range that matters on track exits. Without the dB killer fitted, the GP70-R produces 123 dB at 6,500 rpm: a raw, pressurised racing note that echoes SC-Project's factory MotoGP sound character and leaves no ambiguity about the bike's intent.\u003c\/p\u003e\u003ch2\u003eImportant Safety Notice\u003c\/h2\u003e\u003cp\u003eThis exhaust system is designed exclusively for closed-course competition use.
