Review on Kawasaki Ninja 400 Z400 Slip-On Exhaust System Including Muffler For Improved Performance - Compatible With Models From 2018, 2019, And 2020 by Zachary Cha

Bought a 2021 ninja 400 a few months ago. This is my first bike and wanted to start small. After a few people saying it sounded like a scooter I did some research on bolt on exhausts and found this unit. I watched a few videos online and was prepared for the install. Took about 10 minutes. Wow what a difference. Sounds amazing. I am running it without the baff installed but that's my preference. It's not ear popping loud or annoying it just Sounds how the bike should have stock. The factory parts are heavy compared to the new unit. I have a size 14 shoe and the new install gives me extra room to move my foot further back as well. Oh I forgot to mention it also looks amazing and didn't break the bank. I am very happy with this purchase. Hope this helps you.
