The Arrow Pista 71204PTZ is a full exhaust system engineered from the ground up for the BMW M1000RR K66, blending Arrow's celebrated Italian race heritage with a multi-material construction that looks as purposeful as it performs. 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.
Key Features
- Stainless steel headers for exceptional heat resistance and long-term durability at sustained race pace
- Titanium silencer body reduces unsprung and overall system weight while dissipating heat with exceptional efficiency
- Carbon end caps add structural rigidity and the unmistakably aggressive aesthetic of a circuit-ready machine
- Stainless steel internals throughout ensure the system retains its integrity regardless of session length or ambient conditions
- Removable dB killer allows sound output to be tuned to circuit noise regulations or open-pit trackday requirements
- Total system weight of 5.90 kg contributes directly to improved power-to-weight ratio and sharper handling balance
Design, Finish and Heritage
Arrow 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.
Performance and Engineering
Designed 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.
