Arrow Racing titanium collectors BMW R 1250 GS / Adv 2019-2023

It is a fundamental component of an exhaust system and thanks to them important gains in power and torque are obtained.

They are made of AISI 304 stainless steel and, in the Competition versions, are also available in titanium alloy.

Arrow manifold kits are born from the careful work of our R&D department, thanks to the experience and results accumulated on tracks all over the world. To this fundamental ingredient is added the touch of our "master" prototypers: diameters, curves, passages, section variations, components, welds and layouts are carefully checked to obtain a highly performing, reliable product with the unmistakable Arrow style.

Depending on the engine and its ignition scheme, the best possible configuration is chosen for the grouping of the manifolds up to the terminal. We therefore speak of patterns 4:2:1, 4:2:2, 2:1:2, 4:2:1:2, 3:1:1 and so on; is one of the most important indications to follow when starting to design and build a collector system. To have a flow of gas that is as smooth as possible, the joints between the various components of the manifold kits are made with parts machined from solid with numerical control machines. For the same reason, in addition to being aesthetically perfect, the welds must be minimally "invasive" and must not reduce the passage section of the exhaust gases.
