I was thinking of adding a layer of ensolite as well but havent got any free time to get it done. By the way, there are 4 screws holding the back panel in place (and the light covers). Very easy to get them off and put some in there.I believe it will help to reduce more noise since this area is right on top of the muflers' tips
