At just 1.72 kg, it trims meaningful mass from the tail end of your S1000RR while the dark stainless steel finish gives a purposeful, understated look that ages gracefully through daily and weekend use alike.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eE-number type approval — fully road legal and compliant for everyday street use straight out of the box.\u003c\/li\u003e\n\u003cli\u003eWeighs only 1.72 kg, delivering a noticeable reduction over the stock unit and sharpening the bike's handling balance.\u003c\/li\u003e\n\u003cli\u003eDark stainless steel canister body with stainless steel end cap and internals — resistant to heat, corrosion and the rigours of year-round riding.\u003c\/li\u003e\n\u003cli\u003eRemovable dB killer included, letting you run quieter for commuting or remove it for a more characterful note on a closed circuit.\u003c\/li\u003e\n\u003cli\u003ePlug-and-play fitment onto the OEM header — no cutting, welding or complex modification required for installation.\u003c\/li\u003e\n\u003cli\u003eCompatible with Arrow headers to form a complete exhaust system should you choose to upgrade further down the line.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality and Performance\u003c\/h2\u003e\u003cp\u003eArrow engineers the Pro-Race range at its Italian facility with aerospace-grade production tolerances. The full stainless steel construction — canister, end cap and internals — means there is no compromise between durability and weight. The dark finish on the outer canister is a heat-treated process, not a paint or coating that will flake or discolour after a season of riding. Connection dimensions of 60 mm inlet and 68 mm outlet are matched precisely to the S1000RR K67 exhaust port geometry, ensuring a leak-free seal and consistent back-pressure characteristics.\u003c\/p\u003e\u003ch2\u003eRoad and Track Versatility\u003c\/h2\u003e\u003cp\u003eThe fitted dB killer makes the 71903PRN an easy choice for riders who spend most of their time on public roads but still want the weight and aesthetic advantage of an aftermarket exhaust. When track days come around, the killer is removable in minutes, freeing up exhaust flow and sharpening throttle response across the rev range. For those seeking maximum performance gains, pairing this slip-on with an Arrow header and arranging a dedicated ECU remap is the recommended route to extract everything the S1000RR K67 platform can offer.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis silencer is designed exclusively for the BMW S1000RR K67 across model years 2019 to 2026. It mounts directly to the standard OEM mid-pipe. It is also fully compatible with Arrow's own header pipes, allowing straightforward conversion to a full Arrow exhaust system at a later stage.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePart number: 71903PRN\u003c\/li\u003e\n\u003cli\u003eType: Slip-on silencer\u003c\/li\u003e\n\u003cli\u003eFitment: BMW S1000RR K67 (2019–2026)\u003c\/li\u003e\n\u003cli\u003eCanister material: Dark stainless steel\u003c\/li\u003e\n\u003cli\u003eEnd cap material: Stainless steel\u003c\/li\u003e\n\u003cli\u003eInternal material: Stainless steel\u003c\/li\u003e\n\u003cli\u003eWeight: 1.72 kg\u003c\/li\u003e\n\u003cli\u003eOverall length: 250 mm\u003c\/li\u003e\n\u003cli\u003eInlet diameter: 60 mm\u003c\/li\u003e\n\u003cli\u003eOutlet diameter: 68 mm\u003c\/li\u003e\n\u003cli\u003eApproval: E-number (road legal)\u003c\/li\u003e\n\u003cli\u003edB killer: Included, removable\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Arrow","offers":[{"title":"Default Title","offer_id":53168792338698,"sku":"71903PRN","price":533.12,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/71903PRN_43d96126-c889-4579-92fe-d34cc43769fa.png?v=1780815391","url":"https:\/\/inter-pace.com\/en-ie\/products\/arrow-pro-race-slip-silencer-dark-stainless-steel-bmw-s1000rr-71903prn","provider":"Inter-Pace","version":"1.0","type":"link"}
