Hood sound dampener, should it stay or should it go?

[chris91LX]

I was looking at my engine today and noticed the greasy, oily sound dampener on the underside of the hood. I pulled it off, but as my Pony is in storage until spring, or until the salt is washed off the roads by a steady rain, I can't drive it to see if the sound is bad without it. Anyone have any recomendations as to whether I should keep it or toss it?
