Every dimension, every weld and every material choice traces back to the demands of professional competition — delivering measurable power gains, a dramatic weight saving and a sound that does full justice to the V4 beneath.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVerified performance gains of +9.8 hp and +7.5 Nm of torque at 8,700 rpm over the standard system\u003c\/li\u003e\n\u003cli\u003eWeight saving of 3.9 kg compared to the OEM exhaust — transforming the feel of the chassis and mass centralisation\u003c\/li\u003e\n\u003cli\u003e4-2-1 full titanium header construction with TIG welds laid in a controlled atmosphere for absolute consistency and durability\u003c\/li\u003e\n\u003cli\u003eSC1-R carbon silencer (350 mm) — the flagship unit in the SC-Project range — with removable dB killer (100 dB with \/ 102 dB without at 6,500 rpm)\u003c\/li\u003e\n\u003cli\u003eCompatible with the original lambda sensors, preserving OBD function and simplifying ECU remapping\u003c\/li\u003e\n\u003cli\u003eCarbon end cap, carbon heat shield and carbon solo-seat silencer bracket complete a purposeful, race-ready aesthetic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eConstruction and Materials\u003c\/h2\u003e\u003cp\u003eThe entire header system is fabricated from titanium, chosen for its exceptional strength-to-weight ratio and resistance to the sustained heat cycles a high-revving V4 produces. Spring-loaded joints use metal-capped gasket springs throughout, ensuring a leak-free seal under the harshest track conditions. Every weld is laid by hand in a controlled-atmosphere environment, a production standard borrowed directly from SC-Project's WorldSBK programme.\u003c\/p\u003e\u003cp\u003eThe SC1-R silencer pairs a carbon fibre shell with a carefully tuned internal geometry that SC-Project developed alongside Aprilia Racing. The result is a power curve that pulls cleanly from mid-range and continues building past the redline, complemented by a harmonic, full-throated exhaust note that is as rewarding at trackday pace as it is at full race speed.\u003c\/p\u003e\u003ch2\u003eOn Track\u003c\/h2\u003e\u003cp\u003eFor riders looking to extract the maximum from the RSV4 1100 Factory on circuit, SC-Project recommend pairing this system with a professional ECU remap. The optimised flow characteristics of the 4-2-1 layout respond well to fuelling recalibration, and the gains quoted above were measured on a dyno with the system fully installed and the engine management adjusted accordingly. The dB killer is straightforward to remove, allowing the system to meet most circuit noise limits when fitted, and to run unrestricted when regulations permit.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis system is a direct, precision fit for the following motorcycle:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eAprilia RSV4 1100 Factory — model years 2021, 2022, 2023, 2024\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003ePart number: A27A-TC93C.
