Arrow X-Kone Exhaust 2013-2016 Kawasaki Ninja 250 / 300

X-Kone silencers were designed to be used in Arrow's competition systems. The results and appreciation these silencers received suggested Arrow should create a separate line of standard systems, using a new carbon endcap and designed to fit naked and sportbikes. The internal structure of the silencer is stainless steel, silencer body is Nichrom (an alloy with stainless steel) with a satin finish: can be fitted to stock or Arrow race collectors with required midpipe (71477MI) 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 Arrow 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. Using the X-Kone silencer with Arrow race collectors provides the best performance gains. Systems do not require changing original settings of the ECU or to add a fuel control module however Arrow suggests to check CO levels once the exhaust is installed. X-Kone silencers are street legal for noise with removable baffle.
