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

The ninja 400 is my first bike and I thought it sounded good stock. The second you pop this on It's a whole new world. My favorite is in second gear on deceleration you get so many burbles and small pops. If you go rid of the cat or got any set of headers it would be insane.It's loud without the baffle but It's a good trade off. IMO the bike stock is way to quiet almost dangerously quiet.Installation was a breeze. if you use grease to slip on the mid pipe it will make your life so much easier.Highly recommend this to anyone.
