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

This slip on exhaust surprised me with how great it sounds. You figure you get what you pay for, but in this case you get a LOT for your money! I put this on my '20 Ninja 400 and it sounds SO much better. It was very easy to install, too.

Product came on time, and in perfect condition. I know other reviewers said they had issue getting the mid pipe on, but mine went on without any hammering or modifications needed. It looks amazing on my 2020 z400, and the sound is 10x better than the stock exhaust. Great product.

For only a fraction of the cost of the name brand pipes, this thing does the job! Sleek look, easy install and more than loud enough! Highly recommend!

Gives my Kawasaki Z400 a nice low growl. It was somewhat difficult to install which is why I couldnt give it 5 stars. That's my feedback.

Great product. Sound improvement was from day to nigth. I recommend this product over any similar but more expensive slip on.

Didn’t slip on all the way. And I’m not about to take a hammer to my motorcycle just to install this. Ninja 400 Thanks for attention.

This wasn't very hard to install. I took my time doing it and didn't have any trouble. It's been on for a few months now and sounds great. It's a slightly lower hum than the stock exhaust and louder.

The camera mic does no justice. This thing is loud without the baffle and sounds great. No sense in spending 100s of dollars for a slip on when this one does the job. My neighbors aren’t happy with me right now. Lol

I do not modify my bikes. It is fast enough stock, and you loose any money when you sell. That said, the only weakness of the Ninja 400 is the cannister. It hits your foot and looks awful. Plus it's heavy.This fixed all the problems, plus the sound is improved (if you're into that).

For the price of this exhaust I have no complaints, sounds good, fits well, however it looks a little small, but overall good exhaust. Springs were not fun to get on though, but I’m sure with the right tools they aren’t that bad

I just installed it so can’t comment on long term quality, but initial impression is great. As everyone else says, the midpipe is a tight fit over the stock header pipe. It definitely could have been forced on, but rather than beat it on I used a small tail pipe expander to widen the end of the midpipe just a tiny bit so it slid right on without forcing it. Other than that the fit and finish looks great and everything lined right up. I tested it both with and without the baffle installed. It…
