SC Project Exhaust Kawasaki Z900 A2 S1 Silencer 2025+

Slip-on mufflers have always represented the first step in the tuning process, and within SC-Project’s product range, the S1 muffler stands out as the perfect combination of lightness, design, and sound.

Crafted from high-grade titanium, this muffler delivers an impressive weight reduction of over 60% compared to the OEM exhaust, while increasing engine performance by up to 3.1 hp and 2.0 Nm of torque at 10,700 rpm. It also ensures a consistent improvement in power and torque delivery across the low and mid range.

The exhaust development showcases SC-Project’s unmistakable hallmark: sound. The voice of the four-cylinder engine is enhanced with a deep, aggressive tone, fully compliant with Euro 5+ regulations.

The hyper-aggressive slash-cut outlet, the striking carbon fiber end cap, and the spectacular hand-welded, sector-style link pipe create a design that perfectly complements the Z900’s look. Every detail is meticulously crafted, combining advanced technologies and premium materials to guarantee outstanding durability, top-tier quality, and high performance.

The muffler body features a laser-etched SC-Project logo. To further enhance the Z900’s appearance, the kit includes a high-quality carbon fiber heat shield that completely replaces the OEM component.

Installation is truly plug-and-play, with no need for ECU remapping.
