Arrow Pista Full Exhaust System in Stainless Steel for BMW S1000RR K67 (2019-2026) – 71204PTZ

The Arrow Pista complete exhaust system 71204PTZ gives your BMW S1000RR a thoroughbred race-derived soundtrack and genuine performance gains, all wrapped in a durable stainless steel and titanium construction that stands up to daily punishment as readily as a track day. At 5.90 kg total and supplied with a removable dB killer, it offers the kind of versatility that makes it a sensible long-term investment whether you are threading through traffic or chasing lap times.

Key Features

• Dedicated fitment for BMW S1000RR K67 model years 2019 to 2026 — no adaptation required, direct bolt-on installation.
• Total system weight of 5.90 kg contributes to a meaningful reduction in unsprung and overall mass, sharpening agility and steering response.
• Stainless steel headers deliver heat resistance and corrosion protection for lasting reliability in all conditions.
• Titanium silencer body keeps weight to an absolute minimum while shedding heat efficiently after hard use.
• Carbon end cap adds structural rigidity alongside an unmistakably purposeful aesthetic.
• Stainless steel internals resist corrosion and maintain exhaust flow integrity over the long term.
• Removable dB killer included — quieten the system when regulations or neighbours demand it, remove it for unrestricted track use.

Construction and Materials

Arrow has engineered the Pista system around a multi-material philosophy that puts the right alloy in the right place. The headers, which endure the highest thermal cycling, are fabricated from high-grade stainless steel — tough, scale-resistant and dimensionally stable under sustained heat. The silencer canister transitions to titanium, cutting weight where it matters most and dissipating residual heat rapidly after a session. The carbon end cap finishes the package cleanly, providing additional stiffness without adding grams. All internal baffling uses stainless steel to ensure the flow path stays free from corrosion throughout the system's service life.

Performance and Everyday Usability

Designed with race conditions in mind, the Pista system optimises throttle response and mid-to-top-end power delivery across the S1000RR's rev range. The geometry of the headers and the silencer volume are matched specifically to the K67 engine, so you are not fitting a universal solution — you are fitting a part Arrow engineered for this exact motorcycle. The inlet diameter of 65 mm and outlet of 58 mm have been selected to balance scavenging efficiency with back-pressure characteristics that suit road and track alike. Arrow recommends a bespoke ECU map to unlock the full performance potential of the system.

It is worth noting that this system carries a race-use classification and does not hold road-legal type approval. The included dB killer reduces noise output for informal road or paddock use, but riders should verify local regulations before use on public roads.

Fitment and Compatibility

This system is designed exclusively for the BMW S1000RR with chassis code K67, covering all variants produced from 2019 through to 2026. It is a complete replacement exhaust — headers, mid-section and silencer — and replaces the entire factory system from the engine ports back.
