I actually prefer the Viper non-X more. The up swept is a little bit to much for me, maybe if it was half that height I would like it better. In my opinion it draws the eye up making the bike look higher off the ground. I don't think you have to completely cover the swingarm for it to look good, plus once a lowering shock comes on the market you will see it again anyway.
At the risk of chastisement from my fellow Fury riders, I must be honest and give it a thumbs down. I'm just not a 2 into 1 man. I prefer the dual pipes like the Cobras or the Mayhems like Salty has on his bike. I wish I would've went with the Mayhems.
