Description

The Yoshimura Alpha T Full System Exhaust is a high-performance exhaust system specifically designed to enhance the power and sound of the Kawasaki Ninja 400 and Z400 models. Developed with a focus on racing applications, this system aims to optimize the performance of these popular motorcycles. Owners can expect a maximum horsepower increase of 4.8% and a maximum torque increase of 4.2%. In addition to the power gains, this full system significantly reduces overall weight, shedding over 6 lbs compared to the stock exhaust setup, which contributes to improved handling and acceleration. The exhaust features Yoshimura's exclusive Works Finish, a treatment that imparts a unique golden titanium aesthetic once the system has undergone a heat cycle. This premium finish, combined with the signature Yoshimura sound, provides a distinctive and aggressive auditory experience. For riders intending to compete or remove passenger footpegs for a cleaner race look, an optional black powder-coated aluminum muffler bracket is available. This exhaust system is proudly made in the USA and is compatible with the following Kawasaki models: Ninja 400 from 2018 through 2023, and Z400 from 2019 through 2023. A fitting kit is included for straightforward installation, and no modifications are required. A removable db killer is also supplied, allowing users to adjust the sound level by removing it for increased volume.
