Arrow 71860AO Thunder Exhaust, Aluminum for KTM RC 390 (2017-)

Arrow's 71860AO Thunder Exhaust, Aluminum with Steel End Cap is made specifically for KTM RC 390 (2017-current).

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 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, with removable baffle.

Link this exhaust to the  AR-71667MI Racing Exhaust Link Pipe or AR-71675MI for best performance.
