My muffler mounting is rudimentary. The upstream mount:
The downstream mount is more robust since it shook apart after a while:
I circled an angle profile behind that stabilizes it. Notice that I use the original diesel muffler rubber absorber.

Just called and ordered. The sheet, 36x54 IIRC cost $99 and $30ish to ship to Kansas.
I also ordered their product for sealing up doors. It replaces the plastic vapor barrier and I saw it mentioned somewhere else in the forums.
The lady who answered the phone and took the order sounded like an older German lady which I found somewhat amusing for some reason. She was very friendly and helpful and seemed very knowledgeable of the products as I asked some questions. I guess it was amusing because I don't imagine older german ladies caring all that much about car audio! ha ha

Hi all! I have horizontal metal straps & vertical piping holding my OEM junk foam to the engine bay. Is everyone removing those before starting? Seems like sliding closed cell foam under the existing would be fine too. Thoughts?

I removed all of that stuff in the course of my TDI swap... And with a proper muffler mounting setup isolating the exhaust from the chassis, and an air box channeling the intake noise into the rear vent and out of the engine bay, I think a majority of the diesel clatter is imperceptible from inside the van. You can still hear it quite well outside especially near the back and next to the drivers side vent, but moving down the road it's mostly gone.
Your mileage may vary, but I don't regret not applying anything to replace that nasty stock stuff
