Every component — from the full titanium header to the SC1-R silencer — carries the lineage of factory racing, delivering a weight reduction, a power gain and a sound signature that no street-legal system can match.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDeveloped directly with Aprilia Racing for the official RS 660 Trofeo race programme\u003c\/li\u003e\n\u003cli\u003eFull titanium 2-1 header construction — weight drops from 6.4 kg (stock) to 3.3 kg, a saving of 3.1 kg\u003c\/li\u003e\n\u003cli\u003eMeasured power gain of +3.6 PS and +2.7 Nm, both at 9,250 rpm\u003c\/li\u003e\n\u003cli\u003eDeep, purposeful racing note: 101 dB at 5,250 rpm with dB-killer fitted, 105 dB without\u003c\/li\u003e\n\u003cli\u003eSC1-R silencer available in natural titanium or carbon finish — both with carbon end cap\u003c\/li\u003e\n\u003cli\u003eSupplied with dB-killer, lambda sensor provision, single-seat exhaust bracket, all fixings and springs\u003c\/li\u003e\n\u003cli\u003e24-month official SC-Project warranty included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eThe Trofeo system is not a universal aftermarket exhaust dressed up in racing colours — it is a purpose-built race tool that was shaped alongside the RS 660 from the ground up. The titanium header reflects SC-Project's long collaboration with MotoGP and World Superbike programmes: raw, brushed titanium that ages with character on the track, paired with an SC1-R canister that is available either in matching titanium or in woven carbon. Both finishes are defined by the carbon end cap, giving the system a visual coherence that looks as deliberate on the paddock stand as it does at speed.\u003c\/p\u003e\u003cp\u003eThe single-seat mounting bracket is integral to the design intent. Removing the pillion footpegs is recommended — they are not compatible with this system — and the result is an aggressive, tail-up stance that signals exactly what this machine is built for.\u003c\/p\u003e\u003ch2\u003ePerformance and Sound\u003c\/h2\u003e\u003cp\u003eWith the lambda sensor provision retained and a plug-and-play fit direct from the Aprilia Racing parts programme, installation is straightforward. The 2-1 collector geometry is optimised for the RS 660's parallel-twin characteristics, broadening mid-range torque while the titanium mass reduction lowers rotational and unsprung weight simultaneously. The dB-killer is included for circuits that enforce noise limits, keeping the system at 101 dB at 5,250 rpm — remove it and the system opens to a full 105 dB race note.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis exhaust is designed exclusively for the Aprilia RS 660, model years 2020 to 2024. It is a race-only product with no road type approval.
