WATERWICH Motorcycle Exhaust Muffler Compatible with Kawasaki ninja 400 Z400 2018 2019 2020

For a cheap slip on kit, it surprisingly is well made. Installs perfectly, everything just slips right on with no trouble. And it's sturdy once installed. Hardest part is getting the retention springs on. Little bit of advice on that -- use zip ties. Close them in a circle, slip it over one of the spring hooks, feed a screwdriver thru the zip tie loop, and pull back to hook it on. Then just snip off the zip tie.Sound is pretty decent. It's for my girls 400. Has a deep note, occasional afterfire burble. Much better over stock sound. The sound difference with and without the db killer is minimal, and sounds better without.

Fits the 2024 Kawasaki Ninja 500 PERFECTLY! Nice and deep rumble! Takes about 10 minutes to install. Super Simple!

I bought my '22 Ninja 400 used with an LV10 slip on that was just too loud for me, but the on/off throttle response was much better with the slip-on compared to the stock pipe. This pipe was a cheap and easy solution. It's much quieter than an LV 10, has a tunable removable baffle, and gives the same upgraded on/off throttle response as the LV-10. The baffle is removable, but also has a secondary internal baffle inside of it that can be placed in multiple positions on the baffle or removed to further reduce sound. This gives you the ability to have essentially three different sound levels; open baffle, baffle in, and baffle in with secondary baffle. I chose to remove the secondary baffle but run the main baffle, which makes it just a bit louder than stock. With both baffles in the exhaust is basically as quiet as stock, but with a different sound. I only knocked it one star because the 45° pipe that came with it has the spring mounting tabs positioned off by about 30°, but the pipe still mounted up fine, the springs just run a bit across the pipe. It's a cheap product, so I'm not surprised they're a manufacturing inconsistencies. If you get one of these and have the ability to tack weld, it does come with two extra spring mounts that can be tacked on wherever you need.

Its a nice cheap muffler that sounds really good only down fall is that is cheaply made baffle fell out somewhere while i was riding 30 minutes after installing it now my bike sounds like dirt bike

This needs to have instructions, the spring won’t even stretch long enough to connect . Horrible.
