ARROW X-Kone complete exhaust system, homologated, in black aluminum with stainless steel headers for KAWASAKI Z 650 21-23 | NINJA 650 21-23

ARROW X-KONE 71937XKNW full system in black aluminum with stainless steel headers for KAWASAKI Z 650 21-23 | NINJA 650 21-23

This is the X-KONE system with a carbon end cap, which is the black aluminum model with a stainless steel link pipe and stainless steel headers.

Arrow introduces the new X-Kone silencer line. Originally developed for the Competition and Competition “Full Titanium” lines, they are now also available for mid-displacement naked sportbikes in a homologated version with a removable dB-killer. Noise is controlled by absorption, which lightens the internal structure.

The internals are made of stainless steel and the body is made of satin-finished Nichrom. Depending on the application, X-Kones can be mounted on the original headers or on Arrow headers via a stainless steel link pipe, attaching to the bike's original mount with a bracket welded onto the silencer. Its weight is approximately 2.2 kg, 30-40% less than the original, and they significantly improve performance, whether in the Slip-On version or in a full kit with Arrow headers.

The Arrow X-Kone exhaust does not require any remapping or the use of additional control units, 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, noticeably increasing horsepower and torque.

What material is it made of?

The silencer body is made of aluminum, which allows the exhaust to be much lighter compared to steel. This material also dissipates heat more effectively, which contributes to improved performance. Aluminum is highly corrosion-resistant and has a shiny appearance. In addition, the exhaust features a black finish, which is achieved through a ceramic-based painting process, resulting in a more aggressive look.

The header is made of high-quality austenitic stainless steel, which offers high corrosion resistance, improved high-temperature resistance properties, and perfected formability.

The durability of the materials used for its development is track-tested to ensure optimal road performance.
