ARROW Race Tech Dark Z 650 17-19 71854AKN+71659MI Carbon Full Line System

vehicle type:

 er650h.

collectors collectors and pipes are a most important component of an exhaust system, making it possible to reach very important gains in terms of power and torque.

made in aisi 304 stainless steel and, for competition full titanium systems, in titanium, arrow collectors design comes from the experience gained and the results achieved in years of races at all levels, with the un-replaceable ``touch´´ of the master mechanics working in the r&d:

diameters, sections, bends, section changes weldings and layout are carefully designed and developed on the motorbike to create a product with high performance, durable, reliable and with the unique arrow style.

depending on engine configuration and its spark timing, the layout can be really different as it´s needed to adapt it to changing needs:

that´s why we speak about different schemes like 4:2:1, 4:2:2, 2:1:2, 4:2:1:2 and so on.

to follow one scheme or another is a most important decision, to be taken at the very start of the project, and it will influence all the other steps.

to avoid unnecessary drag on the flow of exhaust gases, all junctions and connections are made using cnc-machined parts.

for the same reason, all welds need to be perfectly made and non-invasive, avoiding any section reduction for the flow of gases.

race-tech exhaust range was the first series of silencers designed with the new diamond-shaped section.

this design replaced (quite completely, but not at all) in the past years the older silencers sections, oval and cylindrical.

the advanced profile (looks like a diamond, with smooth corners) makes it possible to reduce dimensions with respect to an exhaust with a more traditional shape and with an equivalent section surface.

this feature is important in reducing weight and dimensions, increasing the internal volume with excellent advantages in noise damping and high performance.

internal structure is generally made in stainless steel, tig welding.

the internal parts, the sections, the exit pipe and the rear endcap are designed to allow for the smoother flow of exhaust gases possible reducing back-pressure-generated losses.

race-tech silencers are available in titanium, carbon fiber and aluminum.

aluminum is available in 3 different finishes:

transparent anodized, black anodized (``dark´´ version) and white painted (``white´´ version).

rear endcap is available in stainless steel or in carbon fiber.

race-tech silencers are available in a street legal version.
