SC Project Exhaust KTM 990 Duke SC1-X Silencer 2024+
Have your KTM look and sound as it should, straight from the factory, with this beautifully designed SC Project exhaust.
The SC1-X silencer is the perfect match for the aggressive KTM 990 Duke, with an ultralight titanium body, sharp-edged carbon-fibre end cap, and asymmetrical outlet.
It boosts agility with a weight reduction of over 40% (-1.5 kg vs the OEM exhaust) and delivers +1.0 hp and +1.0 Nm at 7700 rpm.
100% Made in Italy, it uses cutting-edge TIG welding in a protected environment and features details like the SC-Project laser-engraved logo.
True to SC-Project tradition, it enhances the KTM twin’s voice with deeper tones while remaining fully Euro 5+ compliant.
The kit is completely plug-and-play and includes a high-quality carbon-fibre heat shield. ECU remapping is not required.
