Every dimension is engineered to the precise fitment requirements of the 2012-2016 RJ15 chassis, making it the natural first step in a serious track-day or race-series build.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePurpose-built stainless steel construction delivers outstanding heat resistance and long-term durability under sustained race conditions\u003c\/li\u003e\n\u003cli\u003e54 mm outlet diameter optimises exhaust gas velocity for improved mid-range and top-end performance\u003c\/li\u003e\n\u003cli\u003eSharper, more immediate throttle response compared to the factory header\u003c\/li\u003e\n\u003cli\u003eDesigned as a direct, precise fit for the Yamaha YZF-R6 RJ15 (2012-2016) — no modification required\u003c\/li\u003e\n\u003cli\u003eRace-use only homologation keeps weight and restrictions to a minimum for maximum track performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality \u0026amp; Performance\u003c\/h2\u003e\u003cp\u003eArrow manufactures the 71473MI from high-grade stainless steel, chosen for its exceptional resistance to the thermal cycling that destroys lesser headers over a season of hard use. The tube geometry has been developed specifically around the RJ15 engine's exhaust timing, producing a more linear power delivery and a noticeably crisper throttle feel from the moment you exit a slow corner. At 3.72 kg, the header contributes to a well-balanced overall exhaust system weight without compromising structural integrity.\u003c\/p\u003e\u003ch2\u003eTrack Use \u0026amp; ECU Mapping\u003c\/h2\u003e\u003cp\u003eThe 71473MI carries race-use only approval and is not road-legal. To extract the full performance benefit and ensure long-term reliability, Arrow strongly recommends an ECU remap or custom mapping session following installation. A correctly matched map allows the fuelling and ignition timing to work in concert with the freer-flowing header, preventing lean conditions and maximising the power gains on offer.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis header is designed exclusively for the following model:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eYamaha YZF-R6 RJ15 — model years 2012, 2013, 2014, 2015, 2016\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003e71473MI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eArrow\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eHeader (exhaust manifold)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eStainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOutlet Diameter\u003c\/th\u003e\n\u003ctd\u003e54 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e3.72 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eApproval\u003c\/th\u003e\n\u003ctd\u003eRace-use only — not road-legal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFitment\u003c\/th\u003e\n\u003ctd\u003eYamaha YZF-R6 RJ15 (2012-2016)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Arrow","offers":[{"title":"Default Title","offer_id":53168808034570,"sku":"71473MI","price":921.06,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/71346MI_9396f90a-3222-4661-b265-e0df45db83d1.png?v=1780816034","url":"https:\/\/inter-pace.com\/fr-mc\/products\/arrow-71473mi","provider":"Inter-Pace","version":"1.0","type":"link"}
