Arrow introduces the new X-Kone range of silencers. Originally developed to be used as a full-line "competition" and "competition full titanium" muffler for track use, the silencer is now available for a naked and sport series. The X-Kone silencer is road-approved with removable baffle, stainless steel internal components and noise reduction by absorption (to reduce the weight of the internal structure). The silencer body is made of Nichrom (stainless steel alloy) with a satin finish. Depending on the application, the X-Kone silencer can be mounted on either the original manifold or the Arrow racing manifold. The muffler is attached to the footrest by means of a bracket welded to the muffler body. The weight of an X-Kone muffler is around 2.2 kg (30% to 40% less than the original muffler), and power and torque output are significantly higher. Installing an X-Kone silencer does not require changing ECU parameters or adding the anECU module. A check on CO levels is nevertheless suggested.
