The SC Project GP70-R Exhaust for the Yamaha YZF-R1 (2017–2019) and R1M is a race-inspired, high-performance upgrade designed to transform the aesthetics, sound, and handling of Yamaha’s flagship superbike. Developed using technology from MotoGP and World Superbike, the GP70-R provides a serious enhancement over the stock exhaust, delivering superior power delivery, weight reduction, and a raw, motorsport-grade soundtrack.
🔧 Design & Build Quality
SC Project builds the GP70-R exhaust using aeronautical-grade materials that guarantee top-tier strength, thermal efficiency, and long-lasting durability. Its construction reflects the precision and performance standards expected in world-class motorsports.
-
Outer Sleeve Options: Choose between lightweight Titanium or Carbon Fiber, both selected for their heat resistance and ability to shed unnecessary weight.
-
TIG Welded Joints: Expert welders use Tungsten Inert Gas (TIG) welding in a controlled environment to ensure each joint is perfectly fused for structural integrity.
-
CNC Machined Components: The exhaust features insert bushings precisely CNC machined from solid blocks, which improves overall durability and fitting accuracy.
-
Signature Racing Look: A round, oversized muffler exit gives the system a bold and aggressive profile, enhancing the bike’s visual edge.
⚙️ Performance Enhancements
Installing the GP70-R exhaust significantly improves the R1’s dynamic performance, particularly in weight, throttle response, and engine breathing.
-
Shed the Weight: The exhaust system is about 6.2 kg lighter than the factory unit. This considerable reduction improves agility, especially during cornering and high-speed transitions.
-
More Responsive Power: Though SC Project doesn’t list exact horsepower figures, riders benefit from enhanced throttle responsiveness and mid-range torque, thanks to improved exhaust flow and reduced backpressure.
-
Uncompromised Sound: This system delivers a raw, track-ready exhaust note. Without a dB-killer, the GP70-R produces a deep and throaty tone—reminiscent of MotoGP bikes—adding to the visceral riding experience.
✅ Compatibility & Intended Use
The GP70-R is engineered exclusively for high-performance riding and track use only. While it provides undeniable performance benefits, it isn’t road legal due to its emissions and noise output.
Model Compatibility:
-
Yamaha YZF-R1 (2017–2019)
-

Due to its racing-spec nature, always check your region’s regulations if you intend to use it outside of closed-course environments.
