SC Project GP-M2 Carbon Fibre Silencer Kawasaki Z900 2025-26

Developed directly from the Moto2 World Championship, the SC Project GP-M2 Carbon Fibre Silencer brings race-proven technology to the Kawasaki Z900.

With its compact round design, carbon fibre construction, and CNC-machined end cap, the GP-M2 delivers an aggressive racing aesthetic matched with outstanding performance improvements.

The GP-M2 provides a substantial weight reduction of 55% compared to the OEM exhaust, cutting 2 kg off the bike while boosting performance with up to +3.2 hp and +2.9 Nm of torque at 7700 rpm. The result is sharper handling, improved agility, and a smoother, more responsive ride across the low and mid-range.

Engine sound has been carefully tuned to highlight the Z900’s four-cylinder character, producing deep, growling tones that remain fully Euro 5+ compliant. Handcrafted TIG welds complete the system, showcasing SC-Project’s dedication to precision and craftsmanship. Installation is plug-and-play, requiring no ECU remapping.
