SC Project S1 Titanium Silencer Kawasaki Z900 2025-26

The SC Project S1 Silencer is designed as the ultimate upgrade for the Kawasaki Z900, combining lightweight titanium construction, aggressive styling, and a deep, resonant exhaust note.

As one of SC-Project’s most iconic slip-on mufflers, the S1 is the perfect blend of race-inspired design and everyday usability. Manufactured entirely from titanium, it achieves a remarkable weight reduction of over 60% compared to the OEM exhaust, while improving both handling and agility. Performance gains include up to +3.1 hp and +2.0 Nm of torque at 10,700 rpm, with a smoother and more consistent power delivery throughout the low and mid-range.

The Z900’s four-cylinder soundtrack is transformed with SC-Project’s signature tone — deep, aggressive, and fully compliant with Euro 5+ regulations. The hyper-aggressive slash-cut outlet, carbon fibre end cap, and hand-welded sector link pipe give the S1 a distinctive racing look, while the included premium carbon fibre heat shield ensures a seamless aesthetic upgrade over the OEM part. Installation is straightforward with no ECU remapping required.
