A fundamental component of an exhaust system and thanks to them will provide important gains in power and torque.
They are made of AISI 304 stainless steel and, for Competition systems, are also available in titanium alloy.
The collectors kit Arrow born from the careful work of our R & D department, strong experience and results accumulated in the tracks around the world. At this crucial ingredient is then added touch of our masters prototypists: diameters, curves, steps, sections changes, components, welding and layout are carefully tested to a high performance, reliable and unmistakable style Arrow.
Depending on the engine and the ignition scheme, you are chosen the best possible configuration for the grouping of the collectors themselves up to the terminal. It So we speak of 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 guidelines to follow when you start to design and implement a collector system. To obtain a flow of gas the more smoothly as possible, the junctions between the collectors of the various kit components are realized with solid machined parts with numerical control machines. For the same reason the welds, in addition to being aesthetically perfect, have to be little invasive and must not reduce the exhaust gas passage section.
