The MotoSport.com Arrow Street Thunder With Mid-Pipe Full System Exhaust Kit includes the Arrow Street Thunder Silencer, an Arrow Mid-Pipe and Arrow Racing Collectors, each with the following features:
Arrow Street Thunder Silencer:
The latest generation of street bikes are made following a precise design and style idea, giving a fundamental importance in using the smaller exhaust systems possible, placed in some "non-conventional" position. These styling and design features have an impact also on aftermarket parts, to use the smallest exhausts possible. Arrow decided to use for several street bike silencers a section initially designed for a completely different "world" and the Street-Thunder range was born.
Street Thunder silencers are available in titanium, carbon fiber and aluminum, with the endcap (with a fully renewed design) available in stainless steel or carbon.
To compensate for the lower internal volume, research and tests have been done on racetracks and in Arrow's R&D, looking for the better materials available in the market for noise reduction.
Street Thunder silencers are light and powerful, they are available as slip-on systems or as a part of the full system (with Arrow collectors).
Arrow offers a wide and complete range of exhausts, for both street and off-road bikes, with great performance and the unique and eye-catching Arrow style. Arrow is committed to making the best products and to give maximum satisfaction to the customer.
Arrow Mid-Pipe for use with Arrow exhaust.
Designed to fit Arrow exhaust to O.E.M. and/or Arrow headers.
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.
