Description

COLLECTORS

It is a fundamental component of an exhaust system and thanks to them important gains in power and torque are achieved.
They are made of AISI 304 stainless steel and, in the Competition versions, they are also available in titanium alloy.
The Arrow collector 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 then added the touch of our "master" prototype makers: diameters, curves, passages, section variations, components, welds and layout are carefully verified to obtain a highly performing, reliable product with an unmistakable Arrow style.
Depending on the engine and its ignition scheme, the best possible configuration is chosen for the grouping of the manifolds themselves up to the terminal.
We therefore speak of schemes 4:2:1, 4:2:2, 2:1:2, 4:2:1:2, 3:1:1 and so on; it is one of the most important indications to follow when starting to design and build a collector system.
To have a gas flow 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, the welds, in addition to being aesthetically perfect, must be minimally invasive and must not reduce the exhaust gas passage section.
