At just 1.93 kg it strips meaningful mass from the tail section while sharpening throttle response and unlocking a genuine step in mid-to-top-end performance — all without sacrificing the legal certification that keeps you on public roads.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eE-mark type approval included: road-legal straight out of the box, no exemptions or paperwork required.\u003c\/li\u003e\n\u003cli\u003eRemovable DB-Killer supplied: run it open on track for maximum sound, refitted on the road to stay within noise limits.\u003c\/li\u003e\n\u003cli\u003eAluminium Dark silencer body keeps weight to just 1.93 kg, reducing unsprung and tail mass for sharper handling.\u003c\/li\u003e\n\u003cli\u003eStainless steel internals resist heat cycling and corrosion across a full season of hard riding.\u003c\/li\u003e\n\u003cli\u003eCarbon end cap delivers a motorsport aesthetic that complements the R1\/M's aggressive bodywork.\u003c\/li\u003e\n\u003cli\u003eSlip-on fitment designed to mate directly with the OEM header — or upgrade to an Arrow header for a full performance system.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePerformance \u0026amp; Build Quality\u003c\/h2\u003e\u003cp\u003eArrow designed the Indy-Race range to satisfy riders who want genuine, measurable gains without dismantling the bike's everyday usability. The 55 mm inlet and 58 mm outlet diameters are optimised for the YZF-R1's exhaust gas flow at high rpm, improving scavenging and translating directly into more responsive throttle pickup. The dark-anodised aluminium canister is both a visual statement and a functional choice: it runs cooler to the touch than bare metal and resists the kerb-side knocks that track days inevitably bring. Arrow's recommendation to run a custom ECU map when fitting this silencer is worth following — the fuelling calibration that comes with the stock exhaust is no longer optimal once the back pressure changes, and a remap will unlock the full performance benefit.\u003c\/p\u003e\u003ch2\u003eRoad \u0026amp; Track Use\u003c\/h2\u003e\u003cp\u003eThe E-mark approval is the defining credential of this particular Arrow variant. Where comparable slip-ons require you to refit a standard silencer for the MOT or technical inspection, the 71829AKN passes as fitted. The included DB-Killer makes the transition between road and track straightforward: remove it in the paddock, replace it before heading home. For riders who want to extend the system further, the Indy-Race canister is fully compatible with Arrow's own YZF-R1\/M headers, creating a matched full-system exhaust with a single mid-pipe junction.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis slip-on silencer fits the following models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYamaha YZF-R1 — model years 2017 to 2026\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R1M — model years 2017 to 2026\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSlip-on installation uses the OEM header connection point.
