I removed the trunk access cover and installed dynamat in the entire exposed area. This includes from the seat transition to the tray, the tray itself, and behind the plastic cover on the trunk entry. It did help out overall, but the Megan's drone still comes through. I couldn't deal and sold mine a few weeks later. Currently stock and I can't hear my exhaust at all with the dynamat installed ...whisper quiet. Trying a modified OEM unit this weekend and I hope it hits the mark.
