Every weld, every contour, and every gram of this system reflects a philosophy of uncompromising race-derived engineering — purpose-built for riders who demand the last fraction of performance on track.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFull 4-2-1 titanium construction across headers and silencer, delivering a weight saving of 4.2 kg over the OEM system\u003c\/li\u003e\n\u003cli\u003eMeasured gains of +9.8 hp and +7.5 Nm of torque (without dB-killer, at 8,700 rpm) for a transformative on-track experience\u003c\/li\u003e\n\u003cli\u003eAggressive race soundtrack: 106 dB at 6,500 rpm with dB-killer fitted; 113 dB at 6,500 rpm without\u003c\/li\u003e\n\u003cli\u003ePrecision TIG-welded titanium headers in a controlled environment for consistent quality and extreme heat resistance\u003c\/li\u003e\n\u003cli\u003eCarbon end cap, carbon heat shield and carbon single-seat silencer bracket for an unmistakably race-focused aesthetic\u003c\/li\u003e\n\u003cli\u003eCompatible with original lambda sensors — plug-and-play installation with no sensor modification required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eSC-Project's heritage in top-flight motorsport is written into every detail of the SC1-R. The titanium's natural raw finish — a hallmark of the finest racing exhausts — develops a characteristic heat tint over time, marking the system as genuinely functional rather than merely decorative. The 250mm silencer profile is lean, purposeful and immediately recognisable as track equipment. Carbon fibre accents on the end cap, heat shield and bracket reinforce the premium character without adding unnecessary mass. This is not a road-legal catalogue part dressed up in race clothing; it is a genuine piece of Aprilia Racing DNA made accessible to the privateer.\u003c\/p\u003e\u003ch2\u003ePerformance and Build Quality\u003c\/h2\u003e\u003cp\u003eThe optimised 4-2-1 exhaust routing improves scavenging across the rev range, sharpening throttle response and pulling harder from mid-range through to the top end. The titanium headers, precision TIG-welded in a controlled atmosphere, resist the thermal cycling that destroys lesser systems over a season of hard track use. Metal-capped sealing springs at every joint maintain a gas-tight connection under sustained high-temperature loading, ensuring the performance figures hold lap after lap. The 250mm canister is sized specifically for maximum power without a dB-killer, making it the choice for closed circuits where sound regulations are either absent or lenient.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis system is engineered exclusively for the following model:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eAprilia RSV4 1100 Factory — model years 2021, 2022, 2023, 2024\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eFor racing use only.
