Stainless steel headers, a titanium silencer body and carbon end caps combine to deliver a system that carries the visual drama of a factory WSB specification build alongside a total system weight of just 5.90 kg.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStainless steel headers for exceptional heat resistance and long-term durability at sustained race pace\u003c\/li\u003e\n\u003cli\u003eTitanium silencer body reduces unsprung and overall system weight while dissipating heat with exceptional efficiency\u003c\/li\u003e\n\u003cli\u003eCarbon end caps add structural rigidity and the unmistakably aggressive aesthetic of a circuit-ready machine\u003c\/li\u003e\n\u003cli\u003eStainless steel internals throughout ensure the system retains its integrity regardless of session length or ambient conditions\u003c\/li\u003e\n\u003cli\u003eRemovable dB killer allows sound output to be tuned to circuit noise regulations or open-pit trackday requirements\u003c\/li\u003e\n\u003cli\u003eTotal system weight of 5.90 kg contributes directly to improved power-to-weight ratio and sharper handling balance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eArrow has built its reputation on supplying race teams at the highest levels of competition, and the Pista series carries that lineage directly to track-prepared street machines. The combination of a brushed stainless header running into the titanium canister creates a visual contrast that signals serious intent, while the carbon fibre end caps reference the same material philosophy found throughout the M1000RR's own chassis and bodywork. Every weld, every joint and every surface finish reflects the precision manufacturing for which Arrow's Pianezza facility is known.\u003c\/p\u003e\u003ch2\u003ePerformance and Engineering\u003c\/h2\u003e\u003cp\u003eDesigned exclusively for race and trackday use, the Pista full system re-routes exhaust gases through optimised header geometry to sharpen throttle response and maximise power delivery across the rev range of the BMW M1000RR's S1000RR-derived engine. The 65 mm inlet and 58 mm outlet dimensions have been selected to balance scavenging efficiency with back-pressure characteristics suited to the M1000RR's high-compression, high-revving character. Arrow recommends a dedicated ECU map to unlock the full performance potential of this system and to ensure fuel delivery matches the improved exhaust flow.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Arrow Pista 71204PTZ is a direct-fit full exhaust system developed specifically for the following motorcycle:\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\u003eNo modifications to the frame or subframe are required.
