Finished in Arrow's distinctive dark-anodised aluminium with a carbon end-cap, this slip-on carries the unmistakable Indy-Race aesthetic — race-bred lineage worn openly on the flanks of the Yamaha YZF-R1 and YZF-R1M (RN32, 2015-2016).\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDark-anodised aluminium canister paired with a carbon end-cap for a sinister, race-inspired look that sets this silencer apart from polished or titanium siblings.\u003c\/li\u003e\n\u003cli\u003eWeighs just 1.93 kg — a meaningful reduction over the factory unit, contributing to improved power-to-weight balance and sharper throttle response.\u003c\/li\u003e\n\u003cli\u003eStainless steel internal components resist the sustained heat cycles of both road and track use, ensuring long-term structural integrity.\u003c\/li\u003e\n\u003cli\u003eSupplied with a DB-killer insert for legal road use, removable for open-class track sessions.\u003c\/li\u003e\n\u003cli\u003eE-number homologation included — street-legal straight from the box without the need for additional paperwork.\u003c\/li\u003e\n\u003cli\u003eDesigned to pair directly with an Arrow header to form a complete exhaust system for maximum performance gains; works equally well on the standard header.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eArrow has been supplying MotoGP and WorldSBK teams since the 1970s, and the Indy-Race line translates that competition knowledge into a road-legal product. The Aluminium Dark finish is not a paint or coating applied over bare metal — the dark anodising is integral to the aluminium itself, meaning it will not flake, chip or fade with heat. The contrast between the matte-dark body and the woven carbon fibre end-cap is deliberate: it mirrors the colour palette of contemporary race machinery and suits the aggressive lines of the RN32-generation R1\/R1M without visual compromise.\u003c\/p\u003e\u003ch2\u003ePerformance and Build Quality\u003c\/h2\u003e\u003cp\u003eAt 250 mm in length, with an inlet diameter of 55 mm and an outlet diameter of 58 mm, the Indy-Race canister is dimensioned to maintain correct exhaust gas velocity for the crossplane-crank R1 engine's firing order. The result is improved throttle response across the mid-range and a more linear power delivery compared to the heavier OEM unit. Arrow recommends a dedicated ECU remap to extract the full performance potential of this silencer — while it is functional on the stock map, a custom mapping will unlock the complete benefit of the freer-flowing exhaust path.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis silencer is engineered specifically for the Yamaha YZF-R1 and YZF-R1M, chassis code RN32, covering model years 2015 and 2016. It mounts directly to the original mid-pipe using the standard connection points — no additional brackets or adapters are required for the solo slip-on fitment. For a full-system upgrade, the 71829AKN is compatible with Arrow's own headers for the RN32 platform, creating a complete Arrow exhaust from collector to tip.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePart number: 71829AKN\u003c\/li\u003e\n\u003cli\u003eWeight: 1.93 kg\u003c\/li\u003e\n\u003cli\u003eSilencer length: 250 mm\u003c\/li\u003e\n\u003cli\u003eOutlet diameter: 58 mm\u003c\/li\u003e\n\u003cli\u003eInlet diameter: 55 mm\u003c\/li\u003e\n\u003cli\u003eSilencer material: Aluminium Dark (dark-anodised aluminium)\u003c\/li\u003e\n\u003cli\u003eEnd-cap material: carbon fibre\u003c\/li\u003e\n\u003cli\u003eInternal components: stainless steel\u003c\/li\u003e\n\u003cli\u003eHomologation: E-number (road legal)\u003c\/li\u003e\n\u003cli\u003eDB-killer: included\u003c\/li\u003e\n\u003cli\u003eFitment: Yamaha YZF-R1 \/ YZF-R1M RN32 (2015-2016)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Arrow","offers":[{"title":"Default Title","offer_id":53168809181450,"sku":"71829AKN","price":570.01,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/71829AKN.png?v=1780816086","url":"https:\/\/inter-pace.com\/products\/arrow-71829akn","provider":"Inter-Pace","version":"1.0","type":"link"}
