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

I've had this exhaust for almost a year now and I have nothing but good things to say about it. First off the sound, well, it's what I love most about my bike now. Before it sounded like a sewing machine, now it sounds alot meaner and beefier. The welds have held up great on my exhaust, unlike some other reviews have stated. The install was very easy. I have no experience on motorcycles and from the time I unpacked everything and got finished installing it was roughly 15-20 minutes. Needless to say it was the best $90 I have spent. Quality is very good, have had zero problems.
