Racing-Inspired DNA

The SC1-R is one of SC-Project’s flagship mufflers, heavily influenced by its MotoGP and WorldSBK development programs. Trusted by top teams across global racing championships, SC-Project brings the same technology and attention to detail into this street-and-track-ready exhaust for the Yamaha R1 and R1M (2017–2019 models).

The SC1-R is more than just a slip-on — it’s a precision-engineered component that transforms both performance and aesthetics, while offering the unmistakable race-inspired soundtrack SC-Project is famous for.

Design & Construction

The SC1-R exhaust features a 250mm-long muffler, striking the perfect balance between compact design and refined performance. It’s available in two material finishes: brushed titanium or matte carbon fiber, both of which are ultra-lightweight and highly durable under extreme conditions.

The end cap is made from autoclaved carbon fiber, designed not only for heat resistance and reduced weight, but also to provide an aggressive, angular aesthetic that complements the R1’s sharp lines. TIG welding throughout the system is beautifully executed, showcasing SC-Project’s world-class craftsmanship.

Inside the muffler, a dB killer is included and can be removed for a louder, freer-flowing setup — ideal for track days or riders who want a raw, unfiltered exhaust note.

Aggressive Sound Profile

One of the biggest draws of the SC1-R is its sound. Paired with the Yamaha R1’s iconic crossplane inline-four engine, this exhaust produces a deep, snarling tone at idle, progressing to a high-pitched wail at full throttle. It’s a raw, mechanical symphony — sharp, aggressive, and unmistakably race-inspired.

With the dB killer installed, the exhaust note is toned down enough for street use, but still significantly more aggressive than the stock system. Remove the baffle, and you’ll experience an authentic MotoGP-style soundtrack that’s guaranteed to turn heads.

This sound isn’t just for show — it also provides more tactile rider feedback. The improved auditory connection between the throttle and the engine makes gear selection, engine braking, and rev-matching more intuitive, especially when pushing hard on track.

Performance & Weight Savings

Though it’s a slip-on system, the SC1-R delivers real performance benefits. By improving exhaust flow and reducing back pressure, riders can expect:

• Crisper throttle response

• Improved midrange torque

• Slight horsepower gains, especially when paired with an ECU tune

• A smoother powerband overall

One of the most noticeable improvements comes in the form of weight reduction. The SC1-R is significantly lighter than the OEM muffler, thanks to its titanium or carbon construction. Less weight hanging off the rear of the bike results in better handling characteristics, particularly in side-to-side transitions — a key advantage on technical tracks and twisty roads.

Easy Installation

Designed specifically for the 2017–2019 Yamaha R1 and R1M models, the SC1-R installs directly onto the factory headers using the included link pipe and mounting hardware. No cutting, welding, or modification is required.

SC-Project ensures that fitment is exact, and the high-quality hardware makes the installation process quick and reliable, even for DIY mechanics. The exhaust mounts securely in the stock position, maintaining a clean, integrated look.

---

Style That Stands Out

Visually, the SC1-R sets your R1 or R1M apart. The short, tapered muffler and exposed welds provide a motorsport-ready aesthetic that mirrors the look of factory superbikes. Whether you opt for the titanium or carbon fiber finish, the system looks like it belongs on a race machine — because it does.

Subtle branding includes a laser-etched SC-Project logo and an engraved stainless steel nameplate — both premium touches that elevate the exhaust’s presentation.

Track-Ready Performance, Street-Savvy Design

While the SC1-R is derived from racing, it’s versatile enough for road use — especially with the dB killer installed. However, it’s important to note that this system is not homologated for street use in all regions, depending on local emissions and noise regulations. Riders should check with local authorities to ensure compliance.

For those who primarily ride on track or use their R1 as a weekend canyon carver, the SC1-R offers the perfect blend of performance, sound, and aesthetics.

The Bottom Line

If you’re looking to unleash the full character of your 2017–2019 Yamaha R1 or R1M, the SC-Project SC1-R 250mm Exhaust is a phenomenal choice. With its lightweight construction, fierce MotoGP-inspired sound, and tangible performance benefits, this slip-on system ticks every box for riders who demand more from their machine.

Whether you’re carving through twisties, setting personal bests at the track, or just enjoying the pure sound of a crossplane four singing at redline — the SC1-R delivers an experience that’s raw, responsive, and relentlessly addictive.
