{"product_id":"arrow-71755kz","title":"Arrow Header with Catalyst Stainless Steel – Aprilia RS 660 (2020–2024) 71755KZ","description":"\u003cp\u003eDesigned exclusively for the Aprilia RS 660 from 2020 to 2024, the Arrow header 71755KZ is crafted from premium stainless steel and features an integrated catalyst to meet Euro 5 emissions standards — making it a fully street-legal upgrade that slots in cleanly with your daily ride. Whether you use it as a standalone improvement or pair it with a matching Arrow slip-on silencer to build a complete system, this header delivers noticeably sharper throttle response and improved power delivery from the outset.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIntegrated catalyst ensures full Euro 5 compliance and legal road use across Europe without compromise.\u003c\/li\u003e\n\u003cli\u003ePremium stainless steel construction provides outstanding corrosion resistance and long service life, even under hard use in all weathers.\u003c\/li\u003e\n\u003cli\u003eWeighing just 3.7 kg, the header keeps unsprung and overall mass low without sacrificing structural integrity.\u003c\/li\u003e\n\u003cli\u003eDirect fitment to the Aprilia RS 660 (2020–2024) with plug-and-play installation — no cutting, fabricating, or specialist tooling required.\u003c\/li\u003e\n\u003cli\u003eFully compatible with Arrow slip-on silencer 71929, allowing you to expand to a complete Arrow exhaust system with matched performance gains.\u003c\/li\u003e\n\u003cli\u003eA custom ECU remap is recommended to unlock maximum power and protect engine longevity when used as part of a full Arrow system.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePerformance \u0026amp; Build Quality\u003c\/h2\u003e\u003cp\u003eArrow's reputation for precision engineering is evident in every weld and bend of the 71755KZ. The stainless steel construction resists the extreme thermal cycling inherent to a parallel-twin header, maintaining its form and finish long after cheaper alternatives have discoloured and fatigued. On the road, the optimised primary pipe geometry supports improved scavenging across the RS 660's rev range, sharpening mid-range torque and extending top-end pull in a way that genuinely changes how the bike feels on a long A-road or a spirited mountain pass.\u003c\/p\u003e\u003ch2\u003eBuilding a Complete Arrow System\u003c\/h2\u003e\u003cp\u003eThe 71755KZ is engineered as the foundation of a full Arrow exhaust system for the RS 660. Paired with the Arrow slip-on 71929, the combination transforms into a cohesive, performance-matched setup. Arrow recommends a dedicated ECU mapping solution alongside the complete system to ensure fuel delivery, ignition timing and throttle response are optimised in harmony — delivering measurable gains rather than marginal improvements.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis header fits the following motorcycle:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eAprilia RS 660 — model years 2020, 2021, 2022, 2023, 2024\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eCompatible Arrow slip-on silencer: 71929 (sold separately).\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eArrow\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart number\u003c\/td\u003e\n\u003ctd\u003e71755KZ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComponent type\u003c\/td\u003e\n\u003ctd\u003eHeader with integrated catalyst\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eStainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e3.7 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEmissions compliance\u003c\/td\u003e\n\u003ctd\u003eEuro 5 (E-number approved)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eAprilia RS 660 (2020–2024)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible slip-on\u003c\/td\u003e\n\u003ctd\u003eArrow 71929\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Arrow","offers":[{"title":"Default Title","offer_id":53168788930826,"sku":"71755KZ","price":1105.51,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/71755KZ.png?v=1780815220","url":"https:\/\/inter-pace.com\/de\/products\/arrow-71755kz","provider":"Inter-Pace","version":"1.0","type":"link"}
