SC Project CR-T Carbon Fibre Stoneguard Grid Silencer KTM 1390 Superduke R 2024-25

The SC Project CR-T Carbon Fibre Stoneguard Grid Silencer is the ultimate racing slip-on for the KTM 1390 Super Duke R.

Developed directly from MotoGP technology, the CR-T is SC-Project’s most iconic exhaust – designed without compromise to deliver raw power, extreme weight savings, and a true racing soundtrack.

This version for the 1390 Super Duke R offers a dramatic weight reduction of over 70%, saving 2.4 kg compared to the OEM system. Performance gains are equally impressive, with +4.8 hp at 8200 rpm and +4.0 Nm at 7900 rpm, along with consistent improvements across the low and mid range. Its oversized outlet and honeycomb stoneguard grid provide an aggressive racing sound output of 103 dB at 5000 rpm – pure MotoGP character brought to the road.

Built with a carbon fibre body and titanium end cap, the CR-T features hand-welded TIG joints, precise assembly, and the SC-Project Reparto Corse riveted aluminium plate. A dedicated carbon fibre heat shield is included, ensuring both function and style. Installation is fully plug-and-play with no ECU remapping required.
