The dark-anodised aluminium body and carbon end-cap combination is not just a styling statement; every material choice is made to reduce unsprung mass, sharpen throttle response and reward the rider who refuses to compromise between street and track.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eE-number type approval included — fully road-legal straight out of the box, with documentation to satisfy technical inspections.\u003c\/li\u003e\n\u003cli\u003eRemovable dB killer lets you dial the sound level to suit road use or track days without permanent modification.\u003c\/li\u003e\n\u003cli\u003eAluminium dark finish silencer body keeps weight to just 2.43 kg, contributing to improved handling and reduced unsprung mass.\u003c\/li\u003e\n\u003cli\u003eCarbon end-cap delivers lasting heat resistance and a purposeful aesthetic that complements the RSV4's aggressive lines.\u003c\/li\u003e\n\u003cli\u003eStainless steel internals provide structural rigidity and long-term corrosion resistance across all riding conditions.\u003c\/li\u003e\n\u003cli\u003ePlug-and-play fitment designed specifically for the 2017-2018 RSV4 platform — no cutting, no fabrication required.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eConstruction and Performance\u003c\/h2\u003e\u003cp\u003eArrow's Race-Tech series represents the brand's commitment to bringing genuine motorsport engineering to road-going machines. The 71744AKN silencer is constructed around a dark-anodised aluminium canister that measures 350 mm in overall length, with a 60 mm inlet and 50 mm outlet diameter. These dimensions are optimised for the exhaust flow characteristics of the RSV4 engine family, ensuring back-pressure remains within the range that supports strong mid-range torque alongside top-end power.\u003c\/p\u003e\u003cp\u003eThe stainless steel internal packing components resist the thermal cycling that causes lesser exhausts to degrade prematurely. Combined with the carbon end-cap — chosen for its low thermal expansion and high temperature tolerance — the 71744AKN is built to withstand extended hard use whether commuting or lapping a circuit.\u003c\/p\u003e\u003ch2\u003eExpanding to a Full System\u003c\/h2\u003e\u003cp\u003eThe Race-Tech slip-on is designed to work exclusively with a compatible Arrow mid-pipe. If you already own an Arrow link pipe for the RSV4 platform, the 71744AKN slots straight in to complete a full Arrow exhaust system. That combination unlocks the full performance potential: measurably improved throttle response and meaningful power gains across the rev range. Arrow recommends a custom ECU mapping session after fitting the complete system to extract maximum performance and ensure fuelling accuracy at every throttle opening.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAprilia RSV4 (2017-2018)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RR (2017-2018)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RF (2017-2018)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eNote: this silencer requires a compatible Arrow mid-pipe and is not designed to connect directly to the OEM header system.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003e71744AKN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSeries\u003c\/th\u003e\n\u003ctd\u003eRace-Tech\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eSlip-on silencer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSilencer Material\u003c\/th\u003e\n\u003ctd\u003eAluminium dark (anodised)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEnd-Cap Material\u003c\/th\u003e\n\u003ctd\u003eCarbon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInternal Components\u003c\/th\u003e\n\u003ctd\u003eStainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e2.43 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOverall Length\u003c\/th\u003e\n\u003ctd\u003e350 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInlet Diameter\u003c\/th\u003e\n\u003ctd\u003e60 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOutlet Diameter\u003c\/th\u003e\n\u003ctd\u003e50 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eApproval\u003c\/th\u003e\n\u003ctd\u003eE-number road approval (dB killer included, removable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFitment\u003c\/th\u003e\n\u003ctd\u003eAprilia RSV4 \/ RSV4 RR \/ RSV4 RF (2017-2018)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Arrow","offers":[{"title":"Default Title","offer_id":53168790503690,"sku":"71744AKN","price":477.19,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/71744AKN2.png?v=1780815302","url":"https:\/\/inter-pace.com\/products\/arrow-race-tech-slip-silencer-aluminium-dark-aprilia-rsv4-rr-rf","provider":"Inter-Pace","version":"1.0","type":"link"}
