The 71829AK canister measures 250 mm in length with a 55 mm inlet diameter and a 58 mm outlet diameter — dimensions that Arrow's engineers have matched precisely to the RN32 mid-pipe geometry. The aluminium shell is robust yet impressively light, and it develops a subtle, purposeful patina over time rather than the heavy oxidation you might see on lesser alloys. Inside, a stainless steel baffle assembly handles the thermal and acoustic demands placed on it by the R1's high-revving engine without warping or discolouring.\u003c\/p\u003e\u003ch2\u003ePerformance on Road and Track\u003c\/h2\u003e\u003cp\u003eWith the DB-Killer removed, the Indy-Race produces the aggressive, raspy exhaust note that the crossplane-crank R1 is famous for — crisp on the overrun, purposeful at mid-range, and genuinely stirring at the top of the rev range. On the road, refitting the DB-Killer brings the noise level within legal limits while preserving the improved throttle response and exhaust flow characteristics. Arrow recommends a dedicated ECU remap to extract the full performance benefit from the freer-flowing exhaust path.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis silencer is a direct-fit replacement for the Yamaha YZF-R1 and YZF-R1M, model year 2015 and 2016 (frame code RN32). It replaces the stock canister at the mid-pipe connection and requires no modification to the frame or subframe. For a complete system upgrade, it can be combined with an Arrow header pipe to form a full matched exhaust installation.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePart number: 71829AK\u003c\/li\u003e\n\u003cli\u003eBrand: Arrow\u003c\/li\u003e\n\u003cli\u003eType: Slip-on silencer\u003c\/li\u003e\n\u003cli\u003eMaterial — canister: aluminium\u003c\/li\u003e\n\u003cli\u003eMaterial — end cap: carbon\u003c\/li\u003e\n\u003cli\u003eMaterial — internals: stainless steel\u003c\/li\u003e\n\u003cli\u003eWeight: 1.93 kg\u003c\/li\u003e\n\u003cli\u003eSilencer length: 250 mm\u003c\/li\u003e\n\u003cli\u003eInlet diameter: 55 mm\u003c\/li\u003e\n\u003cli\u003eOutlet diameter: 58 mm\u003c\/li\u003e\n\u003cli\u003eDB-Killer: included, removable\u003c\/li\u003e\n\u003cli\u003eHomologation: E-number (road legal)\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":53168808952074,"sku":"71829AK","price":570.01,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/71829AK222.png?v=1780816075","url":"https:\/\/inter-pace.com\/en-ad\/products\/arrow-71829ak","provider":"Inter-Pace","version":"1.0","type":"link"}
