The SC-Project S1 Titanium Matt Black Exhaust is a premium slip-on system meticulously crafted for the 2025 Kawasaki Z900. Drawing inspiration from SC-Project’s extensive experience in MotoGP, Moto2, and WorldSBK, this exhaust brings race-proven technology and aesthetics to the street. Designed to enhance performance, sound, and visual appeal, it transforms the Z900 into a sharper, more responsive machine.
🏁 Race-Inspired Design and Premium Materials
The S1 exhaust features a tapered titanium body paired with a matte carbon fiber end cap, combining lightweight strength with a sleek, aggressive look. This design not only reduces weight but also improves heat resistance and durability. The titanium link pipe is welded using T.I.G. (Tungsten Inert Gas) technology, ensuring precise and strong joints. Additionally, CNC-machined titanium bushings provide a secure and reliable fitment. The matte black finish, achieved through high-temperature ceramic painting, offers a stealthy appearance that complements the Z900’s aggressive styling.
⚙️ Performance Enhancements
Upgrading to the S1 Titanium Matt Black exhaust results in notable performance improvements:
-
Power Increase: +3.1 hp at 10,750 rpm
-
Torque Boost: +2 Nm at 10,700 rpm
-
Weight Reduction: Saves approximately 2.65 kg compared to the stock exhaust
These enhancements lead to improved throttle response, quicker acceleration, and a more engaging riding experience.
🔊 Aggressive and Engaging Sound
The S1 exhaust produces a distinctive, deep exhaust note that complements the Z900’s sporty character. At idle, it emits a low, throaty growl, which transitions to a sharp, aggressive tone as the engine revs increase. This sound profile enhances the sensory experience of riding, providing audible feedback that matches the bike’s performance capabilities.
🛠️ Easy Installation and Street Legality
Designed for straightforward installation, the S1 Titanium Matt Black exhaust is a direct-fit replacement for the stock muffler.
