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

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.

Gnarly and good for improving performance. Fit is pretty good, but could never get the pipe to be 100% with not leaking some oil at the head. Pipe is way more durable than stock.

Amazing exhaust for the price! Fits exactly and has everything to install except for high heat silicone l which was an easy purchase. Love how it comes with 3 options for sound and spark arrest Would definitely recommend.
