Unlimited Rider Motorcycle Exhaust Middle Pipe Stainless Steel Mid-Pipe 51mm Adapter Inlet Slip-On Connector for Kawasaki Ninja 400 2018 Ninja400

This fit perfectly on my 2009 er6n! I was able to use a replica akrapovich with this mid pipe adapter!No leaks & great build quality I'm extremely happy with this midpipe. Any 51mm muffler would fit this. I believe this would also fit any ninja 650 08-11

Got this to replaced the broken mid pipe for the anodized racing ninja 400 slip on exhaust because they were taking too long. Fit is as expected, tight but managable. I have yet to ride my 400 since installing but i doubt any issies to arise in the mean time. The weld that failed is a bit better on this mid pipe in comparison. I also think the construction of the mid pipe is different as well... i will do a follow up after maybe 600 miles. Probably a month.

DO NOT BUY THIS I BOUGHT THIS THINKING IT WOULD FIT AND IT DIDNT AND THAN THEY CHARGED ME TO RETURN IT WHICH PISSED ME OFF EVEN MORE

Nice pipe for the price. Fit my 1.680 diameter header perfectly, and my 51mm slip on fit just right.

Quality piece, nice welds and fast delivery but item will not fit a 2018 GSX-750 or 600. The end is the exact same size as the exhaust pipe from the bike so it will not slide down onto factory pipe.

Very good quality fo a great price!

Perfect fit. Easy to install and looks great

+1. Tried it and it does not fit a 2019 Kawasaki Ninja 400 ABS
