ARROW Thunder Slip-On Exhaust System for 2013-2015 KTM 390 Duke (Mid-Pipes Included)
More and more new bikes are designed with very small silencers. moreover, these small silencers are also fitted in “strange” positions: these facts made necessary to use smaller and smaller exhaust systems also in the after market production.
For these reasons Arrow decided to introduce in the Street Bikes silencers range a kind of silencer designed in the first time for the Off-Road program, again with a diamond shape. So the Street-Thunder range was born, a mix of design and technology, one of the most good looking in the market. The difference lies in design of the rear endcaps, available in stainless steel or in carbon fibre.
To balance the reduced volume, a strong work has been done in researching for top level sound absorbent and thermal insulating materials: we cannot list the tests made in the R&D and in the tracks, tests that made possible to Arrow to introduce new technologies in the production process. As usual, also Street Thunder silencers are available in a street legal version with removable dB-killer. And as the “bigger brothers”, Street Thunder is available with canisters in titanium, aluminium or carbon fibre.
