The dynamat (fatmat) is more for sound deadening, it stops the car from rattling... The ensolite that went over the fatmat is a closed cell foam which is more of like a sound proofing.. It made a huge difference in my case since I have long tubes, no cats, xpipe and muffler delete... My car is loud! The combo of the fatmat and ensolite definitely made the cabin quieter...with the radio off I can now enjoy a normal conversation with a passenger, before you would have to talk over the exhaust noise...
I'm sure your situation isn't as drastic as mine so you probably don't ned as much as I used.. Check out raamaudio and talk to rick.. Great guy, very knowledge.. He'll help point you in the right direction
