Constructed entirely in titanium and certified to EC and TÜV standards, the S1 gives you a measurable power gain, a deep racing exhaust note, and a kit that bolts straight on without ECU remapping.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEC and TÜV homologated to Euro 5 — fully legal for road use, dB-killer included as standard\u003c\/li\u003e\n\u003cli\u003e+1.4 hp at 12,000 rpm and +1.1 Nm torque at 12,250 rpm over the stock silencer\u003c\/li\u003e\n\u003cli\u003eWeight saving of 0.3 kg: S1 unit weighs 1.2 kg versus 1.5 kg OEM\u003c\/li\u003e\n\u003cli\u003eFull titanium silencer body and full titanium link pipe for direct fitment to the OE catalyst and header\u003c\/li\u003e\n\u003cli\u003eCarbon end cap with specialist acoustic damping material for a deep, unmistakeable racing tone\u003c\/li\u003e\n\u003cli\u003eNo ECU tuning required — direct bolt-on installation, ready to ride immediately\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHomologation and Legal Compliance\u003c\/h2\u003e\u003cp\u003eThe S1 carries official EC and TÜV approval, conforming fully to Euro 5 emissions and noise regulations. The supplied dB-killer brings the exhaust note within legal limits on public roads while still producing the deep, pressurised sound that defines SC-Project's racing heritage. The homologation card is included in the box, so the paperwork is handled from day one.\u003c\/p\u003e\u003cp\u003eUnlike many performance systems that force a choice between road legality and genuine character, the S1 holds both. Remove the dB-killer for closed circuit use and the character of the full titanium construction becomes immediately apparent.\u003c\/p\u003e\u003ch2\u003ePerformance and Engineering\u003c\/h2\u003e\u003cp\u003eSC-Project's motorsport division has campaigned exhausts in the Superbike World Championship for years, and the S1's architecture reflects that lineage directly. The full titanium link pipe creates a straight, unobstructed connection to the OE catalyst, which is why no remapping is needed — the flow geometry is optimised for the standard fuelling map. The result is a clean, consistent +1.4 hp at 12,000 rpm and a +1.1 Nm torque improvement at 12,250 rpm, precisely where the R1's crossplane inline-four is working hardest.\u003c\/p\u003e\u003cp\u003eHydroforming technology shapes the pipes without seams or welds at stress points, and every joint is finished with TIG welding for long-term durability under sustained high-temperature cycling. The carbon heat shield included in the kit protects surrounding bodywork and rider hardware from the elevated temperatures titanium generates in use.\u003c\/p\u003e\u003ch2\u003eMaterials and Craftsmanship\u003c\/h2\u003e\u003cp\u003eThe silencer canister is full titanium — not a titanium-coated steel unit — chosen for its exceptional strength-to-weight ratio and resistance to corrosion and heat discolouration over time. The carbon fibre end cap is formed with the same precision tooling used on SC-Project's track-only catalogue, providing a visual signature that is immediately recognisable and structurally integral rather than decorative.\u003c\/p\u003e\u003cp\u003eTogether, titanium, carbon fibre, and hydroformed pipework represent SC-Project's benchmark for design and performance in the road-legal slip-on segment.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis exhaust is designed and homologated specifically for the following motorcycles:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYamaha YZF-R1 RN65 — 2020, 2021, 2022, 2023, 2024, 2025, 2026\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R1M RN65 — 2020, 2021, 2022, 2023, 2024, 2025, 2026\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eCompatible with all Euro 5 variants of the RN65 generation.
