Hello Everyone. I also have a Wolverine x4 and this is basically what they use to help it stay cool and quiet. I was thinking mine was louder that expected and when i rode in a friends, I noticed it was much quieter. I did some looking and found some of the panels had fallen off. Bought some new material to replace panels. If it improves the noise of a wolverine this much, I will be using it on my Maverick.
