SC Project 2-1 CR-T Carbon Stoneguard Exhaust System Aprilia RS660 2025-26

The SC Project 2-1 CR-T Carbon Stoneguard Full System is designed for riders chasing maximum performance and race-ready aesthetics.

Fitted with the iconic CR-T carbon fibre silencer, this system delivers a serious power gain of +2.9 hp and +2.6 Nm of torque at 8000 rpm, alongside a 50% weight reduction over the stock system. The variable size stainless steel headers optimise low and mid-range power, transforming the RS 660’s responsiveness and agility on track.

The standout CR-T silencer is enhanced by a honeycomb stoneguard grid, offering aggressive race styling while amplifying the twin-cylinder’s sound to 114 dB at 5250 rpm. Finished with the SC-Project Reparto Corse aluminium riveted plate, this system combines strength, lightweight construction, and unmatched design.

Fully plug-and-play and reversible, it also includes a carbon fibre heat shield for added protection. ECU remapping is recommended, and pairing with the SC-Project Electronic Catalytic Remover (ECR) is strongly advised to prevent ECU errors when the catalyst is removed.
