SC PROJECT S1 Titanium EXHAUST FOR SUZUKI KATANA (2019-2020)

SC PROJECT S1 Titanium EXHAUST FOR SUZUKI KATANA (2019-2020)

The 2019–2020 Suzuki Katana blends retro inspiration with modern sc-project-s1-ti…katana-2019-2020/ engineering, paying homage to the legendary 1980s icon while delivering performance derived from the GSX-R lineage. Sharp styling, responsive power delivery, and everyday usability make it one of the most distinctive middleweight streetfighters on the market. However, one area where the Katana often leaves riders wanting more is the exhaust. The factory unit is bulky, quiet, and lacks the sonic edge to match the bike’s muscular persona.

That’s where the SC-Project S1 Titanium Exhaust comes in—a lightweight, track-inspired slip-on system that completely transforms the Katana’s character. Born from MotoGP and WorldSBK experience, the S1 isn’t just about sound—it’s about raw performance, refined engineering, and pure rider engagement.

Overview: Race-Bred Excellence for the Street

The SC-Project S1 Titanium Exhaust is designed for riders who demand more—more sound, more performance, and more attitude. Made in Italy by a brand trusted in the world’s most elite motorcycle championships, the S1 is a slip-on exhaust that replaces the stock muffler with a premium-grade titanium canister and a CNC-machined end cap. It’s compact, aggressive, and built to perform under pressure.

Designed specifically for the 2019–2020 Suzuki Katana, the S1 fits perfectly into the bike’s edgy, angular design language, while shedding significant weight and unlocking a new level of auditory and mechanical feedback.

Materials & Design: Lightweight Meets Aggressive Aesthetics

Crafted from Grade 2 lightweight titanium, the S1 muffler is built to perform. Titanium offers excellent heat resistance, corrosion protection, and extreme weight savings. The result is an exhaust that is significantly lighter than the stock system—helping improve the bike’s handling, acceleration, and overall ride quality.

Its brushed titanium finish develops a rich patina over time, giving it a custom, high-end look that evolves with use. The CNC-machined exhaust outlet features a signature conical shape and a race-style open tip that reinforces its motorsport DNA. The exhaust’s welds are TIG-precision finished, and every component is meticulously assembled by hand at SC-Project’s headquarters near Milan.

Laser-etched SC-Project branding on the canister completes the package—subtle, clean, and unmistakably premium.

Sound: Bold, Raw, and Unapologetic

Where the S1 Titanium truly shines is in its sound profile. The stock Katana exhaust is quiet and polite—great for compliance, but underwhelming for thrill-seeking riders. With the S1 installed, the Katana gains a deep, throaty growl at idle that rises into a sharp, aggressive bark under acceleration.

The tone is refined yet raw, offering a distinct racebike sound without being overly obnoxious. Under load, the inline-four engine roars with far more character, and every gear shift becomes more engaging. Deceleration adds pops and burbles that inject excitement into every ride.

This exhaust doesn’t just make noise—it amplifies emotion. Every twist of the throttle becomes an event, and every ride becomes an experience.

Performance: Feel the Difference

Though the S1 is a slip-on, its performance impact is immediately noticeable. The freer-flowing design reduces backpressure, allowing the Katana’s engine to exhale more efficiently. The result? Faster throttle response, improved torque delivery in the midrange, and a stronger pull toward the top end.

Weight savings also play a major role. By replacing the bulky OEM muffler with this ultralight titanium unit, the bike sheds unnecessary pounds—improving flickability and agility, especially in quick transitions or urban maneuvering.

For riders looking to extract even more performance, the S1 can be paired with SC-Project’s de-cat mid-pipe and an ECU remap or piggyback tuner. This combination unlocks additional horsepower and torque, particularly in the upper rev range, while further sharpening throttle dynamics.

Installation: Simple, Clean, and Reversible

Installation of the SC-Project S1 Titanium Exhaust on the Katana is straightforward. As a slip-on system, it attaches directly to the stock mid-pipe using the included clamp and mounting bracket—no cutting, welding, or extensive modifications required.

SC-Project designs their systems with precise fitment in mind, so alignment is spot-on and the exhaust mounts securely with minimal effort. The installation can typically be completed in less than an hour with basic tools, making it a perfect weekend upgrade.

Street Legality & Racing Use

The SC-Project S1 Titanium Exhaust is typically offered in a racing configuration, meaning it does not include a dB killer or catalytic converter. As such, it is intended for closed-course or track use only in many regions.

Its aggressive tone and increased sound output may not meet street legal requirements depending on local noise and emissions regulations. Riders should always check with local authorities before installing non-homologated parts on street-registered motorcycles.

That said, for those looking to ride on private roads, at the track, or build a custom machine focused on pure performance, the S1 is an excellent choice.

Why Choose the SC-Project S1 Titanium for Your Katana?

The Suzuki Katana deserves more than just a cosmetic nod to its roots—it deserves performance parts that honor its heritage while enhancing its modern potential. The SC-Project S1 Titanium Exhaust delivers exactly that: striking design, race-inspired sound, tangible performance gains, and a level of craftsmanship that only comes from a brand embedded in motorsport excellence.

This exhaust is for the rider who wants the Katana to sound as good as it looks and perform as sharply as it rides.
