Best one yet!

I have tried few different exhaust but this one gives the deep rumble and it sounds amazing at high RPM. Paring this exhaust with Leo Vince headers, my bike became alive. I highly recommend this exhaust to anyone with a sport bike.
Just one thing that I hope that Leo Vince will fix is the clamp that holds the exhaust and that rubber piece!! That took the most time out of entire installation.

Great value slip-on exhaust

I bought this for my 2022 Kawasaki Ninja 400. Installation was super easy - took me less than 30 minutes. Instructions are clear and simple. It looks great on the bike (I have the white SE version of the Ninja). It is a bit louder than I was expecting (without the baffle), but not obnoxiously loud, and still sounds good. Huge difference from the stock exhaust. Considering the other options on the market, this is definitely the best value exhaust in my opinion.

Excellent sound at a great price.

Gives my little z400 some much needed character. Sounds great, easy to install coming from someone who had never installed a slip on before. 10/10 would recommend.

A good and loud exhaust

Love the look and size of the exhaust amd its loud .Glad to have a db killer with it.
The rubber seat was hard to get on and took some good effort.

Just the right tone for the ninja 400. I love the way the gp corsa gives the bike a more aggressive look and reduces the weight of the stock exhaust. Very impressed. I did have to trim the rubber ring piece and it was a little tough getting onto the metal clamp, but it's doable. Would buy again if needed.

Easy to install. Love the look and sound. Period!!!

My 2023 Ninja 400 with ABS just arrived after 3 months of waiting. I could not stand the sound of stock exhaust, so ordered this affordable, nice looking slip-on exhaust.
OMG it’s so easy to install even thought it’s my very first bike upgrade, and the sound is off the hook.
It took 20 mins for me to remove the stock exhaust but only 5 mins to install this one.

Great sound, easy install

Super easy to install (minus fitting the annoying rubber collar thing onto the cuff). I had ZERO experience and put this on my first bike in about an hour. It was loud and sounded amazing. My 400 sounded like a monster. A friend bought my bike when I upgraded and I still enjoy hearing it!

Perfect look and fit ‘21 Ninja 400

The quality was immediately noticed once I pulled the slip on out of the box. The sound and look of this is amazing. I had originally swapped out a generic slip on and then when I installed this, the deepened, throaty noise just reassured me how great of a purchase this was!
