The Suzuki Katana is more than just a motorcycle—it’s a tribute to one of the most iconic sportbikes in history. Reborn with modern performance, aggressive lines, and a GSX-R1000-derived engine, the 2019–2020 Katana balances heritage and innovation with ease. However, many riders feel the stock exhaust doesn’t quite match the Katana’s bold personality. That’s where the SC-Project Metal Black Exhaust with Anodized Full Black CNC Aluminum End Cap enters the picture.
This exhaust system is more than a visual upgrade—it’s a statement of performance, character, and craftsmanship. Designed and hand-built in Italy by SC-Project, it adds a powerful edge to the Katana, both in tone and appearance. Whether you’re a daily rider or a weekend warrior, this exhaust transforms your machine into something sharper, louder, and more aggressive—just like the Katana was meant to be.
Overview: Race-Inspired, Road-Ready
SC-Project is a name synonymous with world-class exhaust engineering, trusted by top teams in MotoGP, WorldSBK, and endurance racing. Their Metal Black line brings that same racing pedigree to road-going machines like the Katana.
This particular variant—a Metal Black slip-on exhaust with a full black anodized CNC-machined aluminum end cap—offers stealthy styling and a deep, aggressive exhaust note. It’s the perfect blend of form and function, delivering a race-inspired look while enhancing both sound and throttle response.
Designed specifically for the Suzuki Katana, this slip-on muffler connects directly to the stock mid-pipe or optional SC-Project link pipes. It’s a direct fit, requiring no major modifications and making it an ideal upgrade for riders who demand both performance and clean aesthetics.
Design & Build Quality: Stealth Meets Strength
Every aspect of this exhaust is a testament to SC-Project’s attention to detail and engineering excellence. The Metal Black muffler body is constructed from high-grade stainless steel and finished in a durable matte black coating. This treatment resists heat, corrosion, and surface wear while maintaining a clean, understated appearance.
The standout feature is the CNC-machined end cap, made from billet aluminum and anodized in deep black. This component not only looks aggressive but also adds structural rigidity and heat resistance. The clean machining lines and sharp angles give it a purposeful, motorsport-inspired edge that perfectly complements the Katana’s futuristic styling.
Additional design highlights include laser-etched branding, precision TIG welds, and a compact form factor. Compared to the bulky OEM exhaust, this system visually slims the bike’s rear end and adds a track-ready vibe without looking out of place.
Sound & Character: Deeper, Louder, Meaner
Let’s be honest—the stock Katana exhaust is functional but uninspiring. The SC-Project Metal Black muffler changes that the moment you fire up the bike.
At idle, it produces a deep, low-frequency rumble that immediately signals business. As you roll on the throttle, the tone builds into a raw, throaty roar that crackles with character. It’s loud enough to be exciting but refined enough to avoid being obnoxious. The black anodized end cap slightly alters the exit acoustics, giving the bike a sharper bark and a clean overrun note.
While this is a slip-on system, it significantly opens up the exhaust flow, reducing backpressure and letting the Katana breathe more freely. That means better throttle response, smoother roll-on power, and a more responsive engine feel overall.
For those who want even more performance, SC-Project offers compatible de-cat link pipes and full systems that eliminate the catalytic converter. When paired with an ECU remap or tuning module, riders can unlock even more horsepower and torque, especially in the mid-to-high rev range.
Installation: Quick, Clean, and Hassle-Free
Installing the SC-Project Metal Black Exhaust on the Katana is straightforward. Thanks to the slip-on design, there’s no need to cut or weld anything. It comes with all necessary mounting hardware and can be fitted using basic hand tools in under an hour for most riders.
SC-Project engineers each exhaust for perfect alignment with factory mounts, so there’s no guesswork or fussing with fitment. The lightweight construction also makes it easier to handle and install without a second set of hands.
Street Legality & Usage
This version of the Metal Black exhaust is typically sold in racing configuration, meaning it may not be homologated for street use in all regions. It doesn’t include a catalytic converter or dB killer, and the sound output is significantly louder than OEM.
For riders using their bikes on closed courses, track days, or private roads, this system is ideal. However, if you’re concerned about noise regulations or emissions standards, SC-Project does offer street-legal alternatives with removable dB killers and Euro4/Euro5 compliance. Always consult your local regulations before installation.
