Would buy again

Looks great, lighter weight and better quality of sound, particularly once you remove the baffle.

Arrow's craftsmanship is top notch

Arrow's craftsmanship is top notch, and Bill's Exhausts gave me a great deal and worked with me when there was a little hiccup with the order. A special shoutout to Samantha--she's very helpful. A+

This exhaust is top notch!

This exhaust is top notch! Quality is better then any exhaust I've had in the past and would highly recommend it! The sound on the xsr 700 is perfect! Loud but not obnoxious! I've had a bunch of different exhausts for the cp2 motor akra, M4, two bros and this sounds better then all of them by far! There aren't too many exhaust sound clips for this on the cp2 so I was taking a chance and I can say I am not disappointed in any way!!

Easy installation

Easy installation. Sounds good but not crazy loud on a ZX6R.

Long delivery time but worth it

Easy installation. Website picture doesn’t reflect actual item though. It is a carbon fiber can.

LeoVince LV Corsa slip-on exhaust on my Kawasaki Z900

Installed the LeoVince LV Corsa slip-on exhaust on my Kawasaki Z900, and I couldn’t be happier. The build quality is excellent, the sound is absolutely amazing, and the installation was quick and easy.

Right out of the box, you can tell this is a premium product. The Carbon Fiber and finish are top-notch, and everything fit perfectly. Install took very little time, even with basic tools.

The sound quality is perfect — deep, aggressive, and sporty. It completely transforms the character of the Z900 and makes the bike feel alive every time you hit the throttle. No annoying rasp, just a clean, powerful tone that sounds incredible at all RPMs.

For under $500, you simply can’t beat this exhaust. It delivers premium performance, looks, and sound at a fraction of the cost of many competitors. If you’re looking to upgrade your Z900, this is a no-brainer.

Shipping was delayed due to the winter storm but even then it was delivered within a week. Bills Exhaust is my go to.

Highly recommend! 🔥🏍️

Looks Fantastic

Very happy with how the silencer looks on my wife's 2024 Vespa GTV. Its not as light as I thought that it was going to be. But I guess its a sign of the build quality. Sounds very nice with the baffle removed and makes her more visible on the road due to the exhaust tone, which is a must where we live.
