Built entirely from titanium — header, silencer body, end caps and internals — this complete system tips the scales at just 3.10 kg, delivering a meaningful reduction in unsprung and overall mass without a single compromise on structural integrity or heat resistance.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRace-use only homologation — purpose-built for track use, unrestricted by road-noise or emissions legislation, letting the engine breathe freely at every rev.\u003c\/li\u003e\n\u003cli\u003eAll-titanium construction throughout: header, slip-on silencer body, end caps and internal components for exceptional heat dissipation and long service life under sustained track conditions.\u003c\/li\u003e\n\u003cli\u003eTotal system weight of just 3.10 kg, contributing directly to improved power-to-weight ratio and sharper chassis response on the M1000RR K66.\u003c\/li\u003e\n\u003cli\u003eRemovable DB-Killer included — fit it for controlled noise environments, remove it when regulations allow for unrestricted exhaust note and maximum flow.\u003c\/li\u003e\n\u003cli\u003e250 mm silencer length with a 68 mm outlet diameter, dimensioned specifically for the K66 platform to ensure optimal exhaust scavenging.\u003c\/li\u003e\n\u003cli\u003eCustom ECU mapping strongly recommended to unlock the full performance and throttle-response gains this system is capable of delivering.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eConstruction \u0026amp; Performance\u003c\/h2\u003e\u003cp\u003eEvery component of the 71207CP is fabricated from aerospace-grade titanium, a material chosen for its unrivalled combination of tensile strength, resistance to the extreme thermal cycling of race use, and minimal weight. The titanium header feeds directly into the titanium silencer, maintaining consistent exhaust gas velocity across the entire rev range and producing the sharp, linear throttle response that competitive lap times demand. The titanium end caps and internal parts share the same specification, ensuring the whole system ages uniformly even under the punishment of repeated track sessions.\u003c\/p\u003e\u003ch2\u003eTrack Application\u003c\/h2\u003e\u003cp\u003eThis system carries race-use only status — it is not approved for use on public roads and is supplied without any road-homologation documentation. It is the correct choice for BMW M1000RR K66 owners competing in track days, club racing or circuit championships where weight savings, unrestricted exhaust flow and consistent wide-open-throttle performance define the margin between podium and pack. The removable DB-Killer broadens its versatility across noise-sensitive circuits without requiring a second silencer.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe Arrow Pro-Race full exhaust system 71207CP is a direct, bolt-on fitment for the following model:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBMW M1000RR K66 — model years 2021, 2022, 2023, 2024, 2025, 2026\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eNo modification to the mounting points or subframe is required.
