Track-Bred Technology, Street-Ready Execution

SC-Project has earned its reputation on the world stage. The Italian brand supplies exhaust systems to top-tier teams in MotoGP, WorldSBK, Moto2, and more. Every product they offer — including the SC1-S — is born from that racing DNA, distilled into something both beautiful and functional for road riders and track junkies alike.

The SC1-S exhaust is a more compact, sport-oriented design. It’s meant to improve the riding experience across the board — boosting power, enhancing acoustics, and trimming down weight without sacrificing durability or style.

Sleek and Compact Design

The SC1-S features a shortened canister with a sleek, angular silhouette that complements the sharp lines of the R1. Available in both carbon fiber and titanium finishes, the SC1-S is engineered to look as fast as it performs.

Each version includes a carbon fiber end cap, created in-house by SC-Project using autoclave processes. This not only adds a high-end visual touch but also keeps weight to a minimum while resisting high heat from extended performance riding.

Laser-etched SC-Project logos and premium TIG welds make the system feel just as refined as it looks — it’s craftsmanship you can see and feel the moment you unpack it.

Aggressive, MotoGP-Inspired Sound

The Yamaha R1’s crossplane inline-four engine is already known for its distinctive soundtrack. With the SC1-S installed, that character is elevated to a whole new level.

The SC1-S creates a deep, snarling growl at idle that turns into a sharp, resonant howl as you climb the rev range. The short muffler amplifies the raw sound of the engine without distortion, giving you crisp feedback on throttle input and gear changes.

This exhaust is equipped with a removable dB killer, allowing you to tailor the sound output to suit different environments. With it in, the volume is slightly tamed but still very present. Remove it, and you’re treated to a full-throttle race-bike soundtrack that’s bound to raise heart rates and turn heads.

Lightweight Performance Boost

The SC1-S is about more than just style and sound. It’s also a functional upgrade that offers measurable performance advantages. When compared to the stock exhaust, riders will notice:

• Reduced overall weight, improving handling and agility

• Better exhaust flow, resulting in faster throttle response

• Improved midrange and top-end performance, especially when paired with an ECU flash or de-cat mid-pipe

• Enhanced acceleration feel due to reduced back pressure

On the track, this translates to sharper corner exits and more predictable engine behavior under load. On the road, it means smoother throttle transitions and a more connected riding experience.

---

Easy Installation

Designed as a direct bolt-on slip-on system, the SC1-S installs easily to the factory headers of the 2017–2019 Yamaha R1 and R1M. All necessary hardware is included, and installation requires no cutting, welding, or extensive modifications.

The exhaust lines up cleanly with OEM mounting points, keeping your bike’s lines sleek and factory-integrated. Most riders can complete the install in under an hour using standard tools.

Race-Ready Styling with Street Sense

The SC1-S is the exhaust of choice for riders who want race-ready sound and styling without going full race system. Its compact design gives the bike’s rear end a more aggressive and minimalistic appearance. Combined with the weight savings and sound upgrade, it’s one of the most effective ways to transform your R1 or R1M into something that feels and sounds track-ready — even if you’re just hitting your favorite twisties.

Whether you’re prepping for a track day, improving your weekend rides, or just upgrading for the thrill of it, the SC1-S delivers race-level satisfaction in a street-friendly package.

---

Legal Considerations

Like many high-performance aftermarket exhausts, the SC1-S is not street-legal in all regions, depending on local noise and emissions regulations. Riders should verify compliance with local laws before installing and using the system on public roads.

With the dB killer installed, sound levels become more manageable — but always ride responsibly and be aware of local guidelines.

---

The SC1-S vs. Other SC-Project Models

The SC1-S sits slightly more refined than the S1 or SC1-R in terms of sound volume, thanks to its internal design and muffler length. It’s ideal for riders who want an aggressive tone with a slightly more civilized character — perfect for dual-purpose riding.

Where the SC1-R leans louder and track-focused, the SC1-S strikes a more balanced tone without giving up that race-inspired edge.

---

Final Verdict

The SC-Project SC1-S Exhaust is an excellent upgrade for Yamaha YZF-R1 and R1M owners from model years 2017 to 2019. It’s compact, lightweight, beautifully crafted, and brutally effective. The sound is sharp and purposeful, the look is clean and aggressive, and the performance gains are immediate — especially when combined with supporting mods.

If you want to take your R1 to the next level, both visually and mechanically, the SC1-S delivers a total package: race-bred performance, track-ready tone, and Italian craftsmanship that enhances every ride.
