Kawasaki Z1100 - SE (2026) S1 titanium exhaust, matt black

Slip-on mufflers have always represented the first step in the tuning process, and within SC-Project’s product range, the S1 muffler is the perfect blend of lightness, design, and sound standing out as an ideal upgrade to enhance the strong character of the Kawasaki Z1100.

Crafted from high-grade titanium, this muffler delivers an impressive weight reduction of over 75% compared to the OEM exhaust, while boosting engine performance by up to 1,1 hp at 8500 rpm and 0,6 Nm of torque at 7200 rpm. Additionally, it ensures a constant improvement of power and torque delivery in the low and mid range.

The exhaust development reflects SC-Project’s unmistakable signature: the sound. The voice of the four-cylinder engine is enhanced with a deep and aggressive tone in full compliance with Euro 5+ regulations.

The hyper-aggressive slash-cut outlet, the stunning carbon fiber end cap and the exclusive matt black ceramic coating contribute to a design that perfectly matches the Z1100 look. Every detail is meticulously crafted, combining advanced technologies and premium materials to guarantee outstanding durability, top-tier quality, and high performance.

To further enhance the aggressive aesthetics of the Z1100, the muffler body is completed with a laser-etched SC-Project logo, perfectly integrated with the bike’s unique lines.

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