The MotoSport.com Arrow Indy Race Full System Exhaust Kit includes the Arrow Indy-Race Silencer and Arrow Racing Collectors, each with the following features:
Arrow Indy-Race Silencer:
Indy-Race silencers were designed to be used on certain applications, mainly those requiring an under-seat silencer (making it difficult to use Arrow's other available options), but once available, Indy-Race silencers were used also in some "standard" systems.
Design has been inspired by the shape of certain U.S. racetracks (this is the reason for the name of the range) and the section makes it possible to reduce dimensions whilst keeping a good internal volume to damp the noise with a very good power output.
Internal parts are in stainless steel, TIG / MIG welded, the silencer body is available in titanium, carbon fiber and aluminum and a carbon endcap is also available as a choice.
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.
Notes: Actual kit contents are based on fitment. Extended shipping time is due to item being shipped from Italy.
