Lightweight Titanium Construction

The S1 silencer features a lightweight titanium body paired with a carbon fibre end cap. In addition, the kit includes a full titanium link pipe to complete the slip-on system.

SC-Project uses a special high-temperature resistant sound-absorbing material inside the silencer, helping it perform under demanding riding conditions while maintaining its racing-focused character.

Precision Manufacturing and Premium Finish

The S1 muffler reflects SC-Project’s attention to detail through advanced manufacturing techniques.

The brackets and fittings are assembled using T.I.G. welding, ensuring clean and precise joints. Furthermore, the titanium insert bushings are CNC machined for accurate fitment, while the lasered SC-Project logo completes the premium finish.
