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

I liked this exhaust. Nicely polished and the carbon is very nice however the midpipe fits tight and can be difficult to install I've had this exhaust for one month and the welds on the mid pipe broke and have to b e rewelded it looks like the factory did not add filler material to the welds on the mid pipe I still like this exhaust it sounds good I modified the quiet silencer by cutting the back section off so it's more flow through design now I just need a welded midpipe to make it all work
