Sound Deadening
I think I'm getting old because I've found myself getting very tired of a loud car all the time. I found several reviews of people using Peel & Seal, a roof patching material, as an alternative to dynamat. It's apparently very similar, available at Lowes and significantly cheaper.
I figured I'd share incase others were interested in dampening some of the road/exhaust noise. I did under the carpet and the trunk with 4 6"x25' rolls ($75). It really seemed to quiet the car a good bit. I'm thinking about buying another roll or 2 to do the doors. I'll spare you the whole M.net style DIY, but I took a couple pics so you can at least see what the stuff looks like.

I also learned that you don't have to cover it from head to toe, just put a square or chunk on each piece of metal and you will get a significant reduction in noise. You don't have to cover it compelete to damp it.

I did my whole FXT with Raammat which has done well in tests and is one of the most name brand affordable materials. On top of that I used closed cell foam for more deadening.
While you can apply small parts to kill resonance, putting on a complete layer like pdexta does a much better job at killing road noise and exhaust drone which isn't resonance as much as it is simple db.

Was about to start a new thread, but found this one just like it, so here goes.
Just ordered 100 sq/ft of this stuff:
That much for 115 shipped seems like a fantastic deal to me.
Anyway, I plan to completely cover the inside of my heavy pig with this stuff. Like this:
Will post results.

Look up sounddeadenershowdown, I think that guy has the best, most objective information on this subject and I trust his system the most of everything I looked at.
As mentioned in this thread already, the dynamat stuff is just to cut down on resonating panels, and you only need about 25% coverage to achieve that, the rest is just dead weight.
The real luxery car style quiet comes from a sound barrier, like MLV, which is what they use to make sound booths in studios and the like sealed off, which you can buy off ebay from studio supply guys for much cheaper than any other source. Stuff is HEAVY however.
I'm using that very system on my VW project many of you have heard about, the MLV is suspended above a thermal barrier. I want that car cool and quiet.
