At just 4.60 kg for the complete system, it delivers a meaningful reduction in unsprung and overall mass precisely where it counts on circuit, freeing up power and sharpening throttle response in the same stroke.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRace-use only full exhaust system — developed for competitive track use, not road homologated\u003c\/li\u003e\n\u003cli\u003eComplete system weight of 4.60 kg for significant mass reduction over the OEM exhaust\u003c\/li\u003e\n\u003cli\u003eRemovable dB killer included, allowing configuration for paddock sound regulations or unrestricted track sessions\u003c\/li\u003e\n\u003cli\u003eStainless steel headers and slip-on internals paired with a titanium silencer body for an optimal strength-to-weight ratio\u003c\/li\u003e\n\u003cli\u003eCarbon end caps for a purposeful, race-grade finish that resists heat discolouration\u003c\/li\u003e\n\u003cli\u003eOutlet diameter 54 mm, inlet diameter 58 mm, silencer length 250 mm — precision dimensions for maximum flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePerformance \u0026amp; Build Quality\u003c\/h2\u003e\u003cp\u003eArrow's Competition EVO line is built to the same standard used in superbike racing. The stainless steel headers are formed to optimise exhaust gas scavenging across the S1000RR's rev range, improving torque delivery and throttle response without the compromise of a slip-on-only solution. The titanium silencer keeps mass low and handles sustained high-temperature output under racing conditions, while the carbon end caps add a further visual and thermal advantage over aluminium alternatives.\u003c\/p\u003e\u003cp\u003eThe removable dB killer is a practical detail for club racers and track day riders alike — install it for noise-restricted events, pull it for unrestricted sessions without any additional tooling or hardware required.\u003c\/p\u003e\u003ch2\u003eMapping Recommendation\u003c\/h2\u003e\u003cp\u003eArrow and Inter-Pace strongly recommend having the S1000RR remapped or using a dedicated ECU map when fitting this system. A properly calibrated fuelling map ensures optimal throttle response, protects engine longevity, and unlocks the full performance benefit of the Competition EVO setup. Running a race exhaust on a standard map will leave measurable power on the table and may affect reliability under sustained track use.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis system is designed exclusively for the BMW S1000RR K46 produced between 2015 and 2018. It is not compatible with earlier or later S1000RR generations. Always verify the model year and variant before fitting.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePart number: 71141CKZ\u003c\/li\u003e\n\u003cli\u003eBrand: Arrow\u003c\/li\u003e\n\u003cli\u003eSystem type: Full exhaust (complete system)\u003c\/li\u003e\n\u003cli\u003eFitment: BMW S1000RR K46 (2015–2018)\u003c\/li\u003e\n\u003cli\u003eSystem weight: 4.60 kg\u003c\/li\u003e\n\u003cli\u003eSilencer length: 250 mm\u003c\/li\u003e\n\u003cli\u003eOutlet diameter: 54 mm\u003c\/li\u003e\n\u003cli\u003eInlet diameter: 58 mm\u003c\/li\u003e\n\u003cli\u003eHeader material: Stainless steel\u003c\/li\u003e\n\u003cli\u003eSilencer body material: Titanium\u003c\/li\u003e\n\u003cli\u003eSlip-on internals: Stainless steel\u003c\/li\u003e\n\u003cli\u003eEnd caps: Carbon\u003c\/li\u003e\n\u003cli\u003edB killer: Included, removable\u003c\/li\u003e\n\u003cli\u003eIntended use: Race use only\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Arrow","offers":[{"title":"Default Title","offer_id":53168791716106,"sku":"71141CKZ","price":1545.81,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/71141CKZ.png?v=1780815362","url":"https:\/\/inter-pace.com\/products\/arrow-71141ckz","provider":"Inter-Pace","version":"1.0","type":"link"}
