Variable-diameter TIG-welded headers feed the iconic CR-T silencer for a power delivery and soundtrack that no slip-on can replicate — all while shedding 3 kg against the standard system.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRace-proven 2-1 architecture developed directly for the Trofeo Aprilia Racing RS 660 championship\u003c\/li\u003e\n\u003cli\u003eVariable-diameter TIG-welded connections maximise torque across the rev range\u003c\/li\u003e\n\u003cli\u003eSignificant 3 kg weight reduction over the OEM system for sharper handling and improved power-to-weight\u003c\/li\u003e\n\u003cli\u003eIconic SC-Project CR-T silencer delivers an unmistakable, competition-grade exhaust note\u003c\/li\u003e\n\u003cli\u003eCatalyst-free design optimises exhaust gas flow and reduces under-seat temperatures\u003c\/li\u003e\n\u003cli\u003eCompatible with the original pillion footpegs — no compromise to passenger practicality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eConstruction and Finish\u003c\/h2\u003e\u003cp\u003eThe full header assembly is fabricated from AISI 304 stainless steel, chosen for its resistance to heat cycling and long-term corrosion resistance even under sustained track use. TIG welding throughout ensures consistent, gas-tight joins at every junction. A carbon fibre heat shield is fitted to the collector area, providing thermal protection while adding a visual cue straight from the pit lane. Your choice of CR-T silencer — natural carbon or titanium — lets you match the system to your bike's aesthetic without sacrificing a single horsepower.\u003c\/p\u003e\u003ch2\u003eOn Road and Track\u003c\/h2\u003e\u003cp\u003eRemoving the factory catalytic converter and replacing the entire exhaust path with this free-flowing 2-1 system allows the RS 660's parallel-twin to breathe properly. The result is a more responsive throttle, a fuller mid-range, and a top-end that feels noticeably liberated compared to the standard setup. The 3 kg mass reduction sits low and central on the chassis, contributing to more neutral handling — a benefit you will feel from the first corner exit. This system is supplied without a dB killer, so the CR-T voice is unrestricted and entirely characteristic of SC-Project's race-developed products.\u003c\/p\u003e\u003ch2\u003eImportant Notice\u003c\/h2\u003e\u003cp\u003eThis exhaust system is designated Racing Use Only and is not approved for use on public roads.
