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.

last generation of street motorbikes 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 after-market parts, to use the smallest exhausts possible.

arrow decided to use for several street motorbikes´ 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 silencer are light and powerful, they are available as slip on systems or as a part of the full system (with arrow collectors) and are available also in a street legal versions.




Many bikes are equipped with an exhaust valve controlled by a servo motor. When making performance changes involving the replacement of the exhaust or the installation of an additional control unit, it is necessary the elimination of the exhaust valve.
