Run it with your stock slip-on silencer on track days and upgrade at your own pace, or pair it immediately with Arrow slip-ons 71506, 71903 or 71554 for a complete Arrow system.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePrecision-engineered fitment for BMW S1000RR K67 model years 2019 to 2026 — no modification required\u003c\/li\u003e\n\u003cli\u003eHigh-grade stainless steel construction delivers excellent heat resistance and long-term corrosion protection\u003c\/li\u003e\n\u003cli\u003e60 mm outlet diameter optimises exhaust flow and throttle response under race conditions\u003c\/li\u003e\n\u003cli\u003eWeighs just 3.10 kg, providing a noticeable reduction over the heavier factory header\u003c\/li\u003e\n\u003cli\u003eCompatible with the original OEM silencer as well as Arrow slip-ons 71506, 71903 and 71554\u003c\/li\u003e\n\u003cli\u003eDesigned for track use, making it an ideal upgrade for dedicated race and trackday machines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality and Performance\u003c\/h2\u003e\u003cp\u003eArrow has manufactured this header from premium stainless steel, chosen for its ability to withstand sustained high exhaust temperatures without warping, corroding or losing structural integrity over multiple hard sessions. The 60 mm outlet connection ensures a clean, leak-free join whether you retain your factory silencer or bolt on one of the compatible Arrow slip-ons. The result is a system that responds crisply to throttle inputs and maintains consistent back-pressure characteristics throughout the rev range.\u003c\/p\u003e\u003ch2\u003eFlexibility for Track Use\u003c\/h2\u003e\u003cp\u003eOne of the most practical aspects of the 71718MI is how it slots into your existing setup. If you already run the stock silencer on your S1000RR, this header bolts straight on and immediately improves exhaust scavenging. When you are ready to go further, Arrow slip-ons 71506, 71903 and 71554 are all fully compatible, letting you build a complete Arrow exhaust system incrementally rather than in a single outlay. For the best results, a remap or ECU recalibration is recommended after fitment.\u003c\/p\u003e\u003ch2\u003eImportant Notice\u003c\/h2\u003e\u003cp\u003eThis header is approved for race use only and carries no road-legal homologation.
