Arrow 71860AK Thunder Aluminium Slip-On Muffler w/Carbon End Cap for KTM Duke 125/RC 125/Duke 390/RC 390 17-20

Arrow's 71860AK Street Thunder Exhaust, Aluminum with Carbon End Cap is made specifically for KTM Duke 125/390 & RC390 (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  71667MI Racing Exhaust Link Pipe or 71675MI for best performance.
