DescriptionThe whole story▼
Built without compromise for the track, the Arrow Pro-Race Low full exhaust system 71205CP strips every unnecessary gram from your BMW S1000RR K67 and replaces it with race-bred performance. At just 2.92 kg for the complete system — headers, silencer, end caps and internals all in titanium — this is the kind of weight saving that reshapes lap times, not just dyno sheets.
Key Features
- Full titanium construction throughout: header, silencer body, end caps and internal components for maximum heat resistance and minimal mass.
- Complete system weight of only 2.92 kg delivers measurable reductions in unsprung and rotating mass, sharpening both acceleration and handling response.
- Engineered specifically for the BMW S1000RR K67 (2019-2026) — direct bolt-on fitment with no modification required.
- Removable dB killer included, letting you dial noise output to suit pit-lane regulations or open track sessions.
- Low-mount silencer configuration keeps mass centralised and maximises ground clearance for aggressive cornering.
- Developed to deliver improved throttle response and peak power output under sustained race conditions.
Race-Focused Engineering
Arrow's Pro-Race designation is not a marketing label — it reflects a strict race-only homologation. The 71205CP carries no road-use approval and is designed exclusively for closed circuit use where emissions and noise legislation does not apply. The titanium header feeds into a 68 mm outlet silencer measuring 250 mm in length, a compact package that tucks cleanly into the S1000RR's belly fairing profile.
Titanium is the material of choice precisely because it combines the structural rigidity needed to survive repeated high-rpm runs with a thermal tolerance that keeps radiated heat manageable for rider and electronics alike. The internals share the same material, so there is no soft spot in the heat path where a cheaper metal might fatigue over a season of track days.
Tuning Recommendation
To realise the full performance benefit of this exhaust system on the S1000RR K67, Arrow and Inter-Pace strongly recommend having the ECU remapped with a dedicated map matched to the 71205CP. Throttle response, fuelling and peak power figures all benefit substantially from a system-specific calibration.
