Muffler exhaust Arrow Street Thunder 51515AO 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. Removal of Db-killer transforms the silencer from homologated to racing, generating a performance improvement, but lost the approval compliance. The assembly does not require changes to the carburation, mappings or the use of additional units.
NOTES: silencer fit only with Arrow link pipe 51013 for original collector (sold separately)
