Description

SC Project Exhaust Aprilia RS 660 SC1-X 2-1 Trofeo Full System 2025-2026

Have your Aprilia RSV4 look and sound as it should, straight from the factory, with this beautifully designed SC Project exhaust.

The SC-Project Trofeo full-system exhaust for the Aprilia RS 660 is derived from the Aprilia Racing RS 660 Trophy program to offer a true ready-to-race setup.

• 40% lighter than OEM

• +3.6 hp / +2.7 Nm at 9250 rpm

• Stronger torque in low–mid rpm thanks to variable-diameter titanium headers

It uses the SC1-R silencer with removable dB-killer:

• 101 dB at 5250 rpm with baffle

• 105 dB at 5250 rpm without

Built with titanium construction, TIG welds, and CNC billet bushings for precise fit and easy assembly. Silencer available in carbon fibre or titanium, with a race-style riveted SC-Project logo plate.

The kit is plug-and-play and reversible, but ECU remapping is recommended.

• Not road legal in Europe

• Not compatible with passenger footpegs

For bikes with the catalytic converter removed, SC-Project recommends the ECR+ module, which plugs into the OBD socket, clears ECU errors automatically, shows status via LED, and includes an OBD splitter for additional devices.
