What it pairs with

On the F 750 GS and F 850 GS 2021-2024, the link pipe works with the Maxi Race-Tech 72639AKN muffler, ECE approved, and with the 71777MI racing headers. On the F 800 GS and F 900 GS / GS Adventure 2024-2026, it pairs with the four Indy Race EVO mufflers – 72653AKN and 72653AON in "Dark" aluminum, 72653PK and 72653PO in titanium – also ECE approved. Since Arrow diagrams state that all components are interchangeable with original ones, the link pipe can also be mounted while keeping the stock muffler.

Who is it perfect for?

For those who use their F GS on the track or for closed-circuit days and want to free up the central section of the exhaust system, lightening the bike and removing the constriction of the original pipe. It is the part that completes an existing Arrow system: those looking for a solution to always keep on the road should stick to the approved muffler.

Frequently asked questions

Is the 71776MI link pipe approved?
No. On all four model pages of the Arrow catalog, this code carries the Racing mark, and the official Arrow legend defines that mark as: does not comply with any regulations, is not approved for road use, and is only usable on closed circuits. It should therefore be considered a part for track use.

Which BMWs does it fit?
On four applications: F 750 GS and F 850 GS from the 2021-2024 series, which Arrow identifies with vehicle type MG85, and F 800 GS and F 900 GS, also in GS Adventure version, from the 2024-2026 series, identified with vehicle type MG90. The same code appears on all four pages of the official catalog.

What changes compared to the original central section?
The Arrow link pipe replaces the stock central pipe with a constant 50 mm stainless steel pipe, without a lambda sensor or CO sensor port and without a db-killer. It weighs 0.5 kg and is attached to the frame with a welded bracket. As it is not approved, its use remains limited to closed circuits.

Which mufflers does it pair with?
On the F 750 and F 850 GS 2021-2024 with the Maxi Race-Tech 72639AKN muffler and with the 71777MI racing headers. On the F 800 GS and F 900 GS / GS Adventure 2024-2026 with the four Indy Race EVO: 72653AKN and 72653AON in Dark aluminum, 72653PK and 72653PO in titanium. It can also remain paired with the original muffler.

What are its measurements and weight?
Arrow declares an inlet and outlet diameter of 50 mm each and a weight of 0.5 kg. The body is entirely made of stainless steel and the frame attachment is with a welded bracket. The length is not among the data published by the manufacturer, so we do not report it.

Can I keep it mounted for inspection?
No. As it is an unapproved racing component, to ride on the road and to present the bike for inspection, the original central section must be reinstalled. Those who want to stay compliant can only modify the muffler, choosing one of the ECE-marked Arrow models available for their bike.
