Weighing just 2.92 kg across the entire system, this full titanium assembly delivers measurable gains in throttle response and power output while stripping meaningful mass from the motorcycle — a combination that justifies its place in any serious track programme.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFull titanium construction throughout — header, slip-on silencer, end caps and internals — for outstanding heat resistance and a minimal system weight of 2.92 kg.\u003c\/li\u003e\n\u003cli\u003eRemovable dB killer included as standard, allowing you to manage sound levels in the paddock or during noise-controlled sessions without tools.\u003c\/li\u003e\n\u003cli\u003ePurpose-engineered for the BMW M1000RR K66 (2021–2026) for a bolt-on, factory-precise fit with no fabrication or modification required.\u003c\/li\u003e\n\u003cli\u003eOutlet diameter of 68 mm and a canister length of 250 mm optimised for high-rpm flow characteristics on the M 1000 RR platform.\u003c\/li\u003e\n\u003cli\u003eRace-use only specification means every design decision prioritises power delivery and weight reduction over road-going compromise.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality and Materials\u003c\/h2\u003e\u003cp\u003eArrow manufactures the 71205CP entirely from titanium — a material chosen not merely for its weight advantage but for its exceptional resistance to the sustained high exhaust temperatures generated by the M 1000 RR's S 1000 RR-derived engine under race conditions. The header runs in titanium, the silencer body is titanium, and even the end caps and internal components share the same specification. The result is a cohesive, thermally stable system that maintains its structural integrity session after session without the discolouration or warping associated with lesser materials.\u003c\/p\u003e\u003ch2\u003ePerformance and Track Use\u003c\/h2\u003e\u003cp\u003eDeveloped specifically for circuit use, the Pro-Race Low system is calibrated to liberate the M 1000 RR K66's top-end performance rather than simply reducing back-pressure. Throttle response sharpens noticeably across the mid-range and upper rev band, and the 2.92 kg total system weight represents a significant reduction over the OEM assembly — weight saved low and central on the chassis where it improves handling balance most. Arrow recommends pairing this system with a bespoke ECU remap to extract the full performance benefit; this is standard advice for any full system replacement on a modern ride-by-wire superbike and is worth planning into your build budget from the outset.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis system is designed exclusively for the following application:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBMW M1000RR K66 — model years 2021, 2022, 2023, 2024, 2025 and 2026\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003ePlease note: the Arrow 71205CP is a race-use only exhaust system.
