SC PROJECT S1 Titanium EXHAUST FOR YAMAHA YZF R1 (2017-2019) – R1M

For riders who demand the ultimate sc-project-s1-ti…r1-2017-2019-r1m/ in performance, sound, and weight savings, the SC Project S1 Titanium Exhaust is a game-changer. Engineered for the 2017–2019 Yamaha YZF-R1 and R1M, this slip-on exhaust is more than a stylish upgrade — it’s a race-bred component that transforms the character of your superbike.

Born From Racing Pedigree

SC Project is no stranger to the world of high-performance racing. The Italian manufacturer is a trusted name in MotoGP, WSBK, and various other championships, which shows in every component they produce. The S1 series in particular is inspired by MotoGP technology, and it’s designed for maximum performance, lightness, and an aggressive sound signature.

Premium Titanium Construction

Crafted entirely from aerospace-grade titanium, the S1 is incredibly lightweight — one of its most defining features. Compared to the OEM exhaust system, the SC Project S1 delivers significant weight savings, helping to reduce the bike’s overall mass and improve handling dynamics. The weight difference becomes especially noticeable when transitioning quickly between corners or lifting the bike up from full lean.

Titanium isn’t just used for its lightness; it’s also known for its excellent resistance to heat and corrosion. This ensures long-lasting durability and a unique coloration that develops over time with use. The signature blue and purple hues that form after repeated heat cycles give the pipe a distinctly race-inspired aesthetic.

Aggressive MotoGP Sound

One of the standout features of the SC Project S1 is its unmistakable sound. The exhaust delivers a deep, raw, and aggressive tone that completely transforms the Yamaha R1’s already powerful crossplane inline-four engine. At idle, the bike snarls with a deeper, throatier tone. As the revs climb, the exhaust unleashes a scream that is unmistakably MotoGP-inspired.

The sound isn’t just for show, though — it plays a part in rider feedback. With a clearer, more aggressive note, it’s easier to gauge throttle input and engine behavior, making it particularly valuable during spirited riding or on track days.

For riders concerned with noise regulations, it’s worth noting that the SC Project S1 includes a removable dB killer. While the exhaust is primarily designed for off-road or track use, the dB killer helps keep sound levels more street-friendly when needed.

Power Gains and Throttle Response

When paired with a proper ECU tune, the SC Project S1 can unlock real performance gains. By improving exhaust gas flow and reducing back pressure, it enhances throttle response, mid-range torque, and high-RPM horsepower. Riders report a smoother power delivery and a more connected feel between the throttle and rear wheel.

Even without a tune, the S1 slip-on provides a noticeable improvement in responsiveness and sound. But for optimal performance and reliability, especially if running without the catalytic converter, a tune is strongly recommended.

Fit and Finish

Installation of the SC Project S1 on the 2017–2019 Yamaha R1 or R1M is straightforward, with all necessary hardware included in the kit. SC Project designs their systems to be plug-and-play with OEM mounting points, meaning no cutting or fabrication is required.

The welds on the titanium canister and mid-pipe are precise and clean, a testament to SC Project’s high manufacturing standards. The laser-etched logo and carbon fiber end cap add premium touches that elevate the bike’s visual profile.

Track-Ready Performance with Street Style

Whether you’re looking to shave lap times on the track or just want to unleash your R1’s true character on the road, the SC Project S1 delivers. It blends the best of both worlds — race-derived performance and show-stopping style. The shorter, angled canister and exposed titanium piping give the rear end of the bike a sleek, aggressive look that turns heads wherever you go.

Compatibility and Legal Considerations

The SC Project S1 Titanium Exhaust is specifically designed for the Yamaha YZF-R1 and R1M models from 2017 to 2019. It’s a slip-on system, so it retains the stock header pipes and catalytic converter unless used with an aftermarket link pipe or full system upgrade.

It’s important to note that this exhaust is not homologated for road use in many regions due to sound and emission standards. Riders should check their local laws and regulations before installing and using the exhaust on public roads.

Final Thoughts

The SC Project S1 Titanium Exhaust is a premium upgrade for any 2017–2019 Yamaha R1 or R1M rider looking to improve sound, performance, and aesthetics. With its MotoGP heritage, lightweight construction, and visceral sound, it’s a top-tier choice for enthusiasts who want the best from their machine.

Whether you’re tearing up the track or showing off at your next bike night, the S1 delivers on every front — and then some.
