looks awesome and works amazing just a lot of maintenance! if your ok with all the maintenance that comes with a raw pipe then this is an awesome choice but I found it to be a little bit tedious for my liking so I would up going with a nickel plated version

Fits good and tight, no smoke leaks; I will buy again whenever I rebuild another bike.

Great sound and performance. Best silencer for supercross/ arena style tracks. Would highly recommend this silencer to everyone. It's a great buy!

Most awesome sounding silencer ever. Improves throttle response and power all through the powerband... Looks nice also.

Bought for my cr85. Sounds way better and still sounds like a hard core two stroke.

Makes washing the bike a breeze. Just plug it in to nearly any exhaust and never worry about water, dirt and debris running down the exhaust.
