Big Gun 19-23 Kawasaki KX 450F EXO Aluminum Full System Exhaust

If you're looking to get the most out of your 2019-2023 Kawasaki KX 450F's engine, especially when pushing it hard on the track or trails, a full system exhaust like this EXO Series from Big Gun is a solid choice. This system is built to handle the demands of modern, high-output MX engines, aiming to give you a noticeable boost in performance while also improving the sound.

The heart of this system is its unique, large hexagon-shaped aluminum muffler. This design significantly increases the muffler's internal volume compared to stock, which helps to lower operating temperatures and allows for a deeper, more tolerable exhaust tone. Inside, special technology alters sound waves to achieve this sound profile. The inlet is a stamped 304 stainless steel cone, also designed for increased volume and durability. The mid-pipe is made from 304 stainless steel, and the entire system is TIG welded for strong, reliable connections, including reinforced muffler brackets. You'll also find a removable screen-type spark arrestor included, which is important for trail riding, and a black powder-coated stainless steel end tip for a clean look.

Beyond the sound and heat management, this Big Gun EXO Series exhaust is designed to deliver significant horsepower and torque gains across the RPM range. It's a lightweight brushed aluminum muffler, contributing to the overall performance by reducing weight. Keep in mind that this exhaust is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and any specific hardware requirements.
