SC-Project SC1-R Slip-On Silencer for Suzuki GSX-R 1000 (2017-2023) – EURO 4 Approved

Born from SC-Project's involvement in the Superbike World Championship, the SC1-R slip-on silencer is the road-legal racing exhaust your Suzuki GSX-R 1000 deserves. Holding full EURO 4 homologation, it delivers a genuine weight reduction, sharpened throttle response and an unmistakable racing note — all without compromising legal compliance for everyday road use.

Key Features

• EURO 4 road approval ensures full legal compliance on public roads — no grey areas, no compromise
• Removable dB-killer lets you switch between a civilised road sound and an unrestricted MotoGP-derived acoustic character at the track
• Asymmetric diamond-shaped silencer body optimises aerodynamics while giving the GSX-R 1000 a genuinely purposeful, race-derived appearance
• Carbon fibre end-cap treated with specialist heat-dampening material for outstanding thermal resistance at sustained high revs
• T.I.G.-welded titanium connections and CNC-machined titanium inserts deliver factory-grade precision fitment and exceptional long-term durability
• Available in carbon or titanium finish to suit your build aesthetic, each paired with a carbon end-cap

Performance and Build Quality

The SC1-R is not a cosmetic upgrade dressed in racing clothes — it is an engineering exercise in mass reduction and flow optimisation. By replacing the heavy OEM silencer with a unit constructed from ultralight titanium or carbon fibre, the GSX-R 1000 gains measurable agility through reduced unsprung and overall mass. The titanium link pipe is shaped for improved exhaust flow efficiency, translating directly into a sharper, more progressive power delivery across the rev range.

Every weld on the SC1-R is executed by T.I.G. process, the same standard demanded in aerospace and motorsport fabrication. CNC-machined titanium bushings guarantee exact alignment on the original mounting points, eliminating vibration and ensuring a rattle-free installation that lasts the life of the silencer.

Sound Character

With the supplied dB-killer fitted, the SC1-R produces a deep, sporting exhaust note that passes road regulations and remains entirely usable in everyday traffic. Remove the dB-killer at the circuit and the full, unrestrained character of the SC-Project exhaust is revealed — a broad, layered sound that is the direct result of the same design philosophy applied to SC-Project's MotoGP and WSBK programmes.

Important Fitment Note

Due to the increased upward angle of the SC1-R canister compared to the original silencer, SC-Project recommends replacing the standard tail tidy and relocating the indicators to keep them clear of the exhaust outlet. This is a straightforward modification that preserves both aesthetics and legal compliance.
