Arrow Pista Full Exhaust System in Titanium – BMW S1000RR K67 (2019-2026) 71205PTZ

The Arrow Pista 71205PTZ is a full exhaust system shaped by Arrow's racing pedigree and built entirely from aerospace-grade titanium — a material chosen not as a styling exercise but because it delivers the ideal balance of structural integrity, heat resistance and minimum mass. At just 5.20 kg for the complete system, it transforms the weight budget of the BMW S1000RR K67 in a way no slip-on can match, freeing up handling and sharpening every transition from corner entry to drive.

Key Features

• Full titanium construction throughout — header and silencer body both in titanium for a coherent, lightweight system that weighs only 5.20 kg complete.
• Carbon end caps deliver a purposeful, race-bred aesthetic while adding torsional rigidity at the silencer outlet.
• Stainless steel internals ensure long-term durability against the thermal cycling of hard track use.
• Removable dB-killer allows sound levels to be adjusted to circuit regulations without tools, then removed entirely for unrestricted performance.
• Developed specifically for the BMW S1000RR K67 chassis — precise fitment with no modifications required.
• Race-use only homologation: engineered without compromise for track environments where every fraction of a kilogram counts.

Heritage, Finish and Design

Arrow's Pista range carries decades of Italian exhaust craft into a product line that has appeared on World Superbike and Superstock machinery. The natural titanium finish — warmed by the characteristic heat-bluing that develops across the header with use — is as much a mark of authentic race engineering as it is a visual statement. It ages honestly, developing a unique patina that reflects how the system has been used. The carbon end caps echo the premium composite language of the S1000RR's own bodywork, creating a cohesive look between pipe and machine.

Performance and Track Suitability

By replacing the entire stock exhaust path — from headers back — the Pista system removes every restriction in the OEM gas flow route. The 65 mm inlet and 58 mm outlet geometry, combined with the silencer's 300 mm length, are tuned for the S1000RR's inline-four character: strong mid-range response and a sustained top-end pull that suits both the long straights and the rapid gear changes of a lap in anger. Arrow recommends a dedicated ECU remap to unlock the full performance benefit of the freer-flowing system.
