The Arrow 71915PK exhaust silencer is the Indy Race line slip-on with a titanium body and carbon end cap developed for BMW F 900 R and F 900 XR 2020-2024, including A2 versions (Arrow vehicle type 4R90 · 4R90R). On the official Arrow diagram, it bears the EURO5, ECE, and CARB marks: it is homologated for road use. Body length 250 mm, outlet 58 mm, db-killer included, declared weight 1.93 kg.
On the official Arrow page for both bikes, the 71915PK bears the ECE and euro/CARB marks, and the assembly diagram header adds the EURO5 mark. Among the Arrow components for this application, the silencer is approved: the link pipe and headers are marked Racing.
• The Arrow assembly diagram pairs the silencer with the 71729MI mid-pipe, which Arrow marks as Racing (sold separately, not included).
• The 71729MI mid-pipe can also be mounted on the original headers — official Arrow note on the diagram.
• The 71730MI racing headers can also be mounted with the original silencer — second official Arrow note.
• Only the silencer is included in the package: mid-pipe, headers, and standard components are not included.

Mounting and combinations
The official Arrow diagram pairs the silencer with the 71729MI mid-pipe, which in turn mounts on both Arrow 71730MI headers and original BMW ones. Those who want the complete system add the 71730MI racing headers, which Arrow declares can be used even with the stock silencer. Professional installation is recommended: the frame attachment is welded to the body and needs to be aligned before tightening.
Perfect for
For those who own an F 900 R or F 900 XR 2020-2024, want the Arrow sound and styling, and do not want to give up road legality or have issues during inspection. Titanium is the choice for those also seeking weight savings compared to the aluminum of the same line.
