The M4 Exhaust KA4014 is a high-performance slip-on exhaust system engineered for 2018-2026 Kawasaki Ninja 400, 500, and Z models. Featuring a sleek X-96 carbon fiber canister, this exhaust system offers a significant weight reduction of 5 lbs compared to the stock unit, contributing to improved motorcycle agility and performance. Designed to enhance both the sound and performance of your motorcycle, the KA4014 slip-on retains the stock catalytic converter, ensuring compliance with emissions regulations while still delivering an aggressive tone. It comes pre-installed with a Stage 1 "Q8" quiet insert, allowing for a more subdued sound profile if desired.
