Exhaust Muffler R6 Arrow Thunder Approved (from 2017)

Muffler silencer Arrow Street Thunder 71863 was born for the last 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 after-market parts, to use the smallest exhausts possible. Arrow decided to use for several street bikes’ silencers a section initially designed for a completely different “world” and the Street-Thunder range was born. Street Thunder silencers are available for some models 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).

Arrow EU approved exhausts have rear cap removable (Db-killer) and are supplied with certificate of approval to be attached to the vehicle registration certificate. The assembly does not require changes to the carburation, mappings or the use of additional units.

NOTES: Arrow Thunder silencer fit on original and Arrow collectors
