DescriptionThe whole story▼

Drawn directly from SC-Project's decades of MotoGP and Superbike World Championship development, the SC1-R slip-on silencer is a race-bred exhaust solution engineered specifically for the Aprilia RSV4, RSV4 RR and RSV4 RF (2018-2020). Its asymmetric diamond-shaped canister and hydroformed end-cap are unmistakably purposeful, delivering a measurable gain in both power and torque alongside a weight saving of 1.8 kg over the stock unit.

Key Features

  • Titanium variable-taper link pipe maximises exhaust gas flow for improved throttle response throughout the rev range.
  • Hydroformed end-cap and asymmetric diamond-section canister body — the signature SC1-R silhouette, built around aerodynamic efficiency.
  • CNC-machined titanium mounting sleeves ensure a precise, rattle-free fitment that holds firm under sustained track use.
  • Removable dB killer included — run 103 dB for controlled test days or pull it for the full 110 dB race note.
  • High-temperature carbon fibre heat shield included as standard, protecting surrounding bodywork and adding to the race aesthetic.
  • Plug-and-play installation; bracket accommodates both passenger footpeg and solo configurations without modification.

Performance & Build

SC-Project's race department validated the SC1-R on the dyno and the circuit before it ever reached a customer. The SC1-R canister tips the scales at just 1.8 kg — a saving of 1.8 kg against the 3.6 kg OEM silencer — dropping unsprung and high-mounted mass where it counts. On the dyno that translates to +4.2 hp at 13,400 rpm and +1.7 Nm of torque at 11,000 rpm, numbers that are felt most acutely in the final third of every straight. The outer shell is available in two finish options: natural titanium or woven carbon fibre, both shaped around an inner titanium structure that resists heat fatigue across an entire track day without complaint.

Sound Profile

At 5,500 rpm the stock RSV4 exhaust registers 96 dB. Fit the SC1-R with the dB killer in place and the figure rises to 103 dB — deep, authoritative and track-day legal at most circuits. Remove the dB killer and the SC1-R opens up to a full 110 dB race soundtrack. This is not a road-legal exhaust; it carries no homologation certificate and is supplied for closed-circuit competition use only.
