      Homologated Nichrome X-kone Carbon End Cap High Version For 51014MI / KZ Link Pipe And Original Collector

      X-Kone silencers were designed at first to be used in our Competition and Competition Full Titanium systems. The results ad appreciation these silencers got suggested to create a separate line of standard systems, using a new carbon endcap, designed to fit naked and sportbikes. 
      The internal structure of the silencer is in stainless steel, silencer body is in Nichrom (an alloy with stainless steel) with satin finish: depending on the bike X-Kone silencers can be fitted on the original silencers (as a slip on – with an adaptor) and/or on the Arrow collectors (part of the full system) and they are secured to the frame by means of a mount welded on the upper side of the body. Noise damping is achieved by absorption: this enables to reduce the weight and the dimensions of the silencer: the weight of the silencer is about 2.2kg, typically 30/40% less than the OE.

      Even installing the slip on version only helps increasing performance, logically using the X-Kone silencer with Arrow collectors gives the best performance gain. Fitting an X-Kone is easy and fast and these systems do not require to change original settings of the ECU or to add a separate ECU module. 

      Arrow suggests to check CO levels once the exhaust is installed. X-Kone silencers are street legal with removable baffle.

      Link this exhaust to the AR-51014MI Racing Collector for best performance.

      Note: Does not meet CARB (California Air Resources Board) emissions standards. For "Competition" use only
