The MotoSport.com Arrow Pro-Race Full System Exhaust Kit includes the Arrow Pro-Race Silencer and Arrow Racing Collectors, each with the following features:
Arrow Pro-Race Silencer:
Pro-Race silencers design comes from the first prototypes made for MotoGP. Pro-Race silencers are built putting together a conical-shaped part (the main body of the silencer) with a cylindrical ending section (98 mm diameter) and these are available in titanium or nichrom (a stainless steel alloy).
The silencers are secured to the bike by means of mounts welded to the main body (most models).
Their cone-shaped design provides a reduction of dimensions and weight, but it also reduces the overall volume of the exhaust, thus limiting noise damping capabilities and the application on bigger or demanding engines.
Street legal with a removable baffle.
Arrow Racing Collectors:
Collectors and pipes are one of the most important components of an exhaust system, making it possible to reach very important gains in terms of power and torque.
The Arrow collectors design comes from the experience gained and the results achieved in years of races at all levels, with the irreplaceable "touch" of the master mechanics working in the R&D: Diameters, sections, bends, section changes welds and layout are carefully designed and developed on the bike to create a product with high performance, is durable, is reliable and possesses 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 Arrow speaks 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.
Made in AISI 304 stainless steel and, for competition "Full Titanium" systems, in titanium.
To avoid unnecessary drag on the flow of exhaust gases, all junctions and connections are made using CNC-machined parts.
All welds are perfectly made and non-invasive, avoiding any section reduction for the flow of gases.
