I discovered today that I hate putting dynamat in even more than I hate putting headliners in! That tranny tunnel was a BEAR! Spent 4-5 hours on my knees in the garage and got about 1/3 of the floors finished along with one cowl side panel.
I got the Dynamat Ultralite. It's actually not THAT bad but all the compound curves on the floors makes it time consuming to install. The inside of my car looks like a giant Klondike bar!
I figured I'd put the old stuff back in since I have it and it's in good shape. Thanks for the replies!
It took me the better part of a full day to install dynamat throughout the interior and roof. Although I have not done so yet, the plan is to use the carpet underlay in conjunction with the dynamat. With the dynamat alone I can already hear a huge sound reduction when the motor is running, and the roof seems more solid as well. Good Luck!
