Designed in-house by Arrow's race engineering team, this header is the essential first step toward a serious competition exhaust build on the ZX-4RR.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePrecision-engineered stainless steel construction delivers exceptional heat resistance and long-term durability under sustained race conditions.\u003c\/li\u003e\n\u003cli\u003eOptimised primary pipe geometry improves throttle response and delivers a measurable performance increase over the stock header.\u003c\/li\u003e\n\u003cli\u003eCompatible with the standard OEM slip-on silencer, allowing a staged upgrade path without additional outlay.\u003c\/li\u003e\n\u003cli\u003eDesigned to pair directly with the Arrow Slip-On silencer (71963) for a complete Arrow race exhaust system.\u003c\/li\u003e\n\u003cli\u003eRace-use only homologation — purpose-built for track days, club racing, and circuit competition.\u003c\/li\u003e\n\u003cli\u003eCustom ECU mapping is strongly recommended to extract the full performance benefit and ensure long-term reliability.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePerformance on Track\u003c\/h2\u003e\u003cp\u003eThe ZX-4RR is a machine built with circuit performance in mind, and the Arrow 71783MI header honours that intent. By replacing the restrictive OEM pipework with a free-flowing stainless steel header, exhaust scavenging improves materially, helping the ZX-4RR's inline-four breathe more freely at high revs. The gains in throttle pick-up are immediately noticeable from corner exit — exactly where lap times are decided.\u003c\/p\u003e\u003cp\u003eFor the best results, pair the header with the Arrow Slip-On 71963 and commission a bespoke ECU remap. The combination transforms the ZX-4RR's power delivery and gives a clear advantage in any competitive class where exhaust modifications are permitted.\u003c\/p\u003e\u003ch2\u003eBuild Quality\u003c\/h2\u003e\u003cp\u003eArrow manufactures this header in high-grade stainless steel, chosen for its resistance to the extreme thermal cycling that race use demands. Every joint, bend radius, and flange dimension is engineered to OEM-level fitment precision, so installation is straightforward and secure without modification. The finish withstands discolouration and corrosion far longer than standard mild-steel alternatives, keeping the engine bay looking as purposeful as it performs.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis header is engineered specifically for the following model:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eKawasaki ZX-4RR — model years 2023, 2024, 2025, 2026\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eCompatible slip-on silencer options:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOEM standard slip-on silencer (retained from existing fitment)\u003c\/li\u003e\n\u003cli\u003eArrow Slip-On silencer, part number 71963\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eArrow\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003e71783MI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Type\u003c\/th\u003e\n\u003ctd\u003eRace exhaust header\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eStainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFitment\u003c\/th\u003e\n\u003ctd\u003eKawasaki ZX-4RR (2023-2026)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompatible Silencer\u003c\/th\u003e\n\u003ctd\u003eOEM slip-on or Arrow 71963\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eApproval\u003c\/th\u003e\n\u003ctd\u003eRace use only — not road legal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eECU Mapping\u003c\/th\u003e\n\u003ctd\u003eRecommended for optimal performance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Arrow","offers":[{"title":"Default Title","offer_id":53168796729610,"sku":"71783MI","price":1049.45,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/71783MI.png?v=1780815616","url":"https:\/\/inter-pace.com\/es-pe\/products\/arrow-71783mi","provider":"Inter-Pace","version":"1.0","type":"link"}
