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

Easy install. Watched a couple youtube videos to get the general idea. Bought the Harbor Freight pipe expander but didn’t need it has everything slipped together without a hitch. I am running with the baffle and it is a little louder than stock which is fine with me. I mostly bought it for the weight savings, some extra room for my right foot on the pegs and the cool factor. Don’t know if it has improved or reduced performance as I didn’t feel much of a change in acceleration.
