A titanium canister, hydroformed carbon fibre end cap and TIG-welded construction deliver a measurable performance gain alongside a weight saving of 1 kg over the stock unit — all while retaining full Euro 5 road approval.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eTitanium silencer body: exceptional strength-to-weight ratio with an unmistakable racing aesthetic straight out of the crate\u003c\/li\u003e\n\u003cli\u003eHydroformed carbon fibre end cap: aerodynamically optimised profile that resists heat and adds structural rigidity without adding mass\u003c\/li\u003e\n\u003cli\u003eTIG-welded joints throughout: motorsport-grade precision welding for long-term durability under sustained high-RPM use\u003c\/li\u003e\n\u003cli\u003ePlug-and-play fitment: exhaust valve outlet fully compatible with the original ECU and wiring loom — no remapping required for installation\u003c\/li\u003e\n\u003cli\u003eCarbon fibre heat shield included: protects surrounding bodywork and rider while completing the race-replica appearance\u003c\/li\u003e\n\u003cli\u003eEuro 5 homologated: road-legal across the EU and UK, supplied with a homologation card\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePerformance Gains\u003c\/h2\u003e\u003cp\u003eThe SC1-R is not merely a cosmetic upgrade. Independent testing on the Aprilia RSV4 1100 Factory shows a gain of +1.8 hp at 13,000 rpm and +1.4 Nm of torque at 7,500 rpm compared with the standard silencer. Power delivery is enhanced across the entire rev range from 5,000 to 13,000 rpm, sharpening throttle response on the way out of slow corners and extending the top-end rush that defines the RSV4 character. The complete unit weighs 4.6 kg versus 5.6 kg for the stock piece — a 1 kg reduction that improves the bike's mass centralisation and handling agility.\u003c\/p\u003e\u003ch2\u003eSound Character\u003c\/h2\u003e\u003cp\u003eThe SC1-R produces a deep, full-bodied V4 note that enriches every ride without crossing into antisocial territory. The tone is distinctly purposeful at low speeds and builds into a proper racing soundtrack at higher revs, all within the sound levels permitted under Euro 5 legislation. It is the correct balance between daily usability and genuine emotional engagement.\u003c\/p\u003e\u003ch2\u003eBuild Quality and Materials\u003c\/h2\u003e\u003cp\u003eSC-Project manufactures the SC1-R in Italy using production standards drawn directly from its WorldSBK and MotoGP programmes. The titanium canister is formed and TIG-welded by hand, giving each unit a characteristic brushed-metal finish that develops its own patina over time. The hydroformed carbon fibre end cap is produced using a high-pressure forming process that ensures consistent wall thickness and eliminates weak points at stress-concentration zones. The included carbon fibre heat shield is finished to the same standard and mounts without modification to the original bracket points.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis silencer is designed as a direct slip-on replacement for the following model:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eAprilia RSV4 1100 Factory — model years 2021, 2022, 2023, 2024\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eThe exhaust valve outlet is compatible with the original Aprilia ECU and wiring harness, making installation straightforward without specialist tools or electronic modifications.\u003c\/p\u003e\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSC-Project SC1-R slip-on silencer — titanium, part number A27A-91T\u003c\/li\u003e\n\u003cli\u003eConnecting pipe with exhaust valve outlet\u003c\/li\u003e\n\u003cli\u003eCarbon fibre heat shield\u003c\/li\u003e\n\u003cli\u003eSingle-seat exhaust mounting bracket\u003c\/li\u003e\n\u003cli\u003eMounting springs and fitting hardware\u003c\/li\u003e\n\u003cli\u003eSC-Project laser-etched logo\u003c\/li\u003e\n\u003cli\u003eSC-Project decal set\u003c\/li\u003e\n\u003cli\u003eHomologation card — Euro 5 road approval\u003c\/li\u003e\n\u003cli\u003e24-month official SC-Project warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePart number: A27A-91T\u003c\/li\u003e\n\u003cli\u003eType: slip-on silencer\u003c\/li\u003e\n\u003cli\u003eCanister material: titanium\u003c\/li\u003e\n\u003cli\u003eEnd cap: hydroformed carbon fibre\u003c\/li\u003e\n\u003cli\u003eHeat shield: carbon fibre\u003c\/li\u003e\n\u003cli\u003eSC weight: 4.6 kg\u003c\/li\u003e\n\u003cli\u003eStock weight: 5.6 kg\u003c\/li\u003e\n\u003cli\u003eWeight saving: 1 kg\u003c\/li\u003e\n\u003cli\u003ePower gain: +1.8 hp at 13,000 rpm\u003c\/li\u003e\n\u003cli\u003eTorque gain: +1.4 Nm at 7,500 rpm\u003c\/li\u003e\n\u003cli\u003eHomologation: Euro 5\u003c\/li\u003e\n\u003cli\u003eFitment: Aprilia RSV4 1100 Factory 2021-2024\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SC-Project","offers":[{"title":"Default Title","offer_id":53168758522122,"sku":"A27A-91T","price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/A27A-91T.png?v=1780813800","url":"https:\/\/inter-pace.com\/ja\/products\/sc-project-a27a-91t","provider":"Inter-Pace","version":"1.0","type":"link"}
