Arrow Pro-Race Titanium Slip-On Silencer BMW S1000RR K67 (2019-2026) 71903PR

Engineered for the demands of the track and refined for the road, the Arrow Pro-Race Titanium slip-on silencer for the BMW S1000RR K67 strips back unnecessary weight and pushes the S1000RR's exhaust note into genuinely race-bred territory. At just 1.22 kg, this is a meaningful, measurable upgrade — one that sharpens throttle response and transforms the character of the bike from the moment it fires up.

Key Features

• Full titanium construction throughout — canister, end cap and internals — delivering exceptional heat resistance, corrosion immunity and an authentic race aesthetic.
• Featherweight 1.22 kg silencer mass for a noticeable reduction in overall bike weight and improved handling dynamics.
• E-number road approval as standard, so you ride it to the circuit, remove the db-killer for track sessions, then ride home.
• Removable db-killer allows instant transformation between street-legal noise levels and unrestricted race sound.
• Direct bolt-on fitment to the OEM header or any compatible Arrow header — no cutting, no fabrication, plug-and-play installation.
• Extendable to a full Arrow exhaust system by pairing with a matching Arrow header for maximum power and throttle response gains.

Race Pedigree, Real-World Capability

The Pro-Race series sits at the top of Arrow's performance exhaust range, developed in direct partnership with racing programmes where weight and durability are non-negotiable. Every gram of material is justified — the all-titanium build does not simply look the part, it endures the sustained high temperatures of track use that would compromise lesser alloys. The natural titanium finish develops its own heat-patina character over time, marking each silencer with the proof of genuine use.

For riders targeting lap times, pairing the 71903PR with a compatible Arrow header and a dedicated ECU remap unlocks the full performance potential of the S1000RR's four-cylinder engine. Arrow recommend a purpose-developed mapping to optimise fuelling and ignition timing across the rev range when running this silencer.

Build Quality

The 71903PR is constructed entirely from high-grade titanium: the main canister, the end cap and all internal components. This all-titanium approach eliminates the weight penalty of stainless steel alternatives while providing superior thermal management. The inlet diameter of 60 mm and outlet diameter of 68 mm are sized to maintain the exhaust gas velocity that underpins mid-range torque, not just peak power.

Fitment and Compatibility

The Arrow Pro-Race Titanium slip-on 71903PR is a direct replacement for the standard silencer on the following motorcycle:

• BMW S1000RR K67 — model years 2019, 2020, 2021, 2022, 2023, 2024, 2025 and 2026
