ARROW X-Kone homologated exhaust in black nichrome for KTM DUKE 990 24-25

ARROW X-KONE 71973XKN silencer in black nichrome for KTM DUKE 990 24-25

Arrow presents the new X-Kone line of silencers. Originally developed for the Competition and Competition “Full Titanium” lines, they are now also available for mid-displacement sports nakeds in a street-legal version with a removable dB-killer. The sound is controlled by absorption, which lightens the internal structure.

The internals are made of stainless steel, and the body is made of satin Nichrome. Depending on the application, the X-Kone silencers can be mounted to the original headers or the Arrow headers using a stainless steel link pipe, securing to the original bike mount via a bracket welded to the silencer. Weighing approximately 2.2 kg—30-40% lighter than the original—they significantly improve performance, whether in the Slip-On version or as a full kit with Arrow headers.

The Arrow X-Kone exhaust does not require any mapping modifications or the use of an additional ECU, although it is recommended to check CO levels. This high-end exhaust is a masterpiece of engineering and design, offering a perfect combination of power, style, and quality. It maximizes gas flow and optimizes engine performance, notably increasing power and torque.
