Arrow presents its new range of X-Kone exhaust silencers. This exhaust silencer was originally developed to be used as part of \"Competition\" and \"Competition Full Titanium\" exhaust systems for track use, and is now available for a range of naked and sport bikes. X-Kone exhaust silencers are certified for road use with a removable baffle, internal stainless steel components and noise reduction by absorption (to reduce the weight of the internal structure). The body of the exhaust silencer is made of Nichrome (stainless steel alloy) with a satin finish. Depending on applications, X-Kone exhaust silencers can be mounted to the original collector or the Arrow racing collector. The exhaust silencer is secured to the footrest using a mount which is welded to the silencer body. An X-Kone exhaust silencer weighs around 2.2 kg (30% - 40% less than original silencers), and provides significantly improved power and torque. Fitting an X-Kone exhaust silencer does not require changing the ECU settings or adding an ECU module. A check on CO levels is recommended nevertheless.
