Have had an overall great experience with the LV10 on my Ninja 500, all the bolts stay tight and theres no rattling. I enjoy the sound quality since my stock exhaust was so quiet. Zero problems, high quality, and I had a fast shipping experience.

Very nice, very loud. Although, would benefit more pairing it with the db killer.

Great pricing through the official Leo Vince website, fast shipping, and super easy to install. The deer, and other drivers that may have not previously paid attention to me, now hear me coming and know I'm there! Super lightweight design shaved 6 pounds off my bike. Perfect! Simply perfect!

Sounds amazing, not too loud and gives a throatier rumble. Huge step up from stock. Build quality is excellent. Install instructions were minimal and left room for interpretation but its simple enough to figure out if you know how to complete an easy puzzle.

This thing is dope asf my bike went from sounding like the jetsons family car to a trex mating with a lawnmower! Easy install and looks clean asf. Made my bike sound so good I started riding like a pro lasted all of 30 mins before I crashed my bike but best 30 mins ever!

First time bike owner. My 2020 Ninja 400 was a lot more quiet than I expected with the stock exhaust. I started watching exhaust reviews on YouTube and the best reviews kept pointing me back to the Lv10. I ordered one and it was here in 2 days and was not disappointed with the sound or the quality. Thanks for a great product.

This slip on was very easy to install and fit perfectly. Since purchasing i have put 2800 miles on the bike and it still sounds just as great as day one. Currently im looking at different options of leo vince products for my wifes bike

The exhaust is perfectly loud. Exactly what I wanted. It’s beautiful. The Installation was super easy. The quality is top tier. And the most important thing is that it ROARS. Just like LeoVince says.

It's quiet loud, but an overall improvement to the sound. As some people noted before, around 3-4k rpm, it doesn't sound very happy, but the pops on the downshifts are very nice.
