Review on Upgrade Your KAWASAKI Ninja 400 with ISTUNT Motorcycle Slip on Half Exhaust System Muffler Pipe: Full Glossy Black 2018-2021 by Adam Gambel

Installation was easy and uncomplicated, but no instructions were included! Luckily it goes right where the stock exhaust was, so everything just fits. Sounds a lot better than the stock exhaust. I didn't want to pay over $200 just for the exhaust acoustics and this sub $100 exhaust seems to fit the bill. It also looks great with the color of my bike. No complaints so far but if anything changes I'll let you know.
