MotoGP Heritage in Every Detail

SC-Project is a name trusted on the world’s biggest racing stages. From MotoGP to WorldSBK, their systems are engineered for podium-level performance. The SC1-R series is a result of years of racing innovation — refined for real-world riders.

Unlike many race-only systems, the 350mm SC1-R Carbon is designed to balance track-ready aggression with everyday practicality. It’s ideal for riders who split their time between street and circuit.

Premium Carbon Fiber Construction

This version of the SC1-R features a beautifully made carbon fiber canister, measuring 350mm in length. The longer design offers a slightly more subdued and rounded tone compared to the more aggressive 250mm version.

The carbon fiber weave has a matte finish that exudes a race-inspired look. This material isn’t just for aesthetics — it’s extremely light and resistant to heat and stress. The end cap is also made of carbon, adding durability and sleek styling.

Every weld is done with precision. The exhaust is finished with a laser-etched SC-Project logo and a stainless steel nameplate for a premium touch.

Deep, Raw, and Refined Sound

Let’s face it — sound is a major reason to upgrade your exhaust. The SC1-R Carbon does not disappoint.

Thanks to the 350mm length, the tone is deep, bass-heavy, and smooth, especially at low and mid RPMs. It’s more controlled than shorter, louder systems — perfect for riders who want to enjoy an aggressive tone without disturbing every neighborhood.

At idle, the crossplane R1 engine produces a deep growl. Roll on the throttle, and it builds to a sharp, ferocious roar at high RPMs. The removable dB killer allows you to adjust the sound level to your needs. Keep it in for everyday use or remove it for full-on track day madness.

Performance That Goes Beyond Sound

The SC1-R isn’t just about sound and looks — it also delivers measurable performance gains. Even as a slip-on, it improves exhaust flow and reduces back pressure.

Here are some of the key benefits:

• Quicker throttle response

• Smoother acceleration throughout the rev range

• Better midrange torque and top-end power

• Reduced overall weight for improved handling

The longer 350mm muffler offers a more linear power curve, making it perfect for street riders who want balance without sacrificing edge. With an ECU tune or de-cat pipe, the performance jump becomes even more noticeable.

Even without tuning, most riders report a crisper throttle feel and better responsiveness in everyday riding.

Straightforward, Bolt-On Installation

Installation of the SC1-R is simple. The 350mm version fits directly onto the stock headers of 2017–2019 Yamaha YZF-R1 and R1M models. It includes a stainless link pipe and mounting bracket for a clean, factory-style fit.

No cutting, welding, or ECU flashing is required. This makes it a true plug-and-play upgrade. Most riders can install it at home with basic tools.

The exhaust mounts seamlessly to factory points, and the carbon fiber finish integrates beautifully with the R1’s aggressive design.

Built for Both Street and Track

What makes this exhaust stand out is its versatility. While it’s built on racing principles, the 350mm muffler offers more practicality than many shorter systems.

The longer design helps tame the volume slightly, making it suitable for daily rides and long trips. But it still maintains that signature SC-Project edge when you open it up.

With the dB killer installed, it’s road-friendly in many settings. Remove it, and the full sound experience is unleashed — perfect for closed-course use or spirited weekend rides.

Legal Considerations

The SC1-R Carbon is not road-legal in all areas due to sound and emissions regulations. Riders should check local laws before using it on public roads. It’s primarily designed for track use or off-road applications in regions with strict compliance standards.
