Review on 🏍️ Enhance Your Kawasaki Ninja 400 with Unlimited Rider Motorcycle Exhaust Middle Pipe - Stainless Steel Mid-Pipe 51mm Adapter Inlet Slip-On Connector (2018 Ninja400) by Paul Zimmer

Got these to replace a broken center pipe for an anodized Racing Ninja 400 that's slipping on the exhaust because they lasted too long. Landing tight as expected, but doable. I have yet to ride my 400 since installing it, but I doubt there will be any problems in the meantime. The fancy weld on this mid-pipe is a bit better in comparison. I also think the design of the middle tube is also different. log off after 600 km. Probably a month.
