I used Xtreme dynamat for the 69 and then went back with gluing carpet foam down. That really insulated the heat and noise.

I went to Lowes for cheap carpet pad and glued it down with 3M General Adhesive. I do that in every car that I build, comes from the rod building I do.

are you saying that you use both? or do you just use carpet padding?

As far as the heat goes, are your exhaustpipes and muffler/s too close to your floors?... should have a air gap and heat sheilds.The last thing you want is to be cruising down the road and have your carpet catch fire.

I used Dynamat Extreme on the floorpan and added a layer of Dynamat Extremeliner in the footwells. The front piece of carpet fits a little loose, but you can't tell with the floormats in place.

Spames.....I use Super Dynamat in the foot wells and tranny hump, then cover the whole thing in 3/8" carpet padding. The carpet padding seems to give the carpet a nice fit and feel plus insulates heat and sound. My 69 is a convertible without chambered pipes, but mufflers tucked up as close as I can get them.

I have headers on the 69 and they flow back close and parallel to the foot drop. This completely takes care of the problem. I have been doing interiors for all kinds of muscle cars, street machines and street rods and use this method profusely. Nary a complaint.

Oh Lord....you folks are paying too much for reduced noise and heat.Try looking at www.b-quiet.com at what they have to offer.They have this product called "brown bread" that outperforms anything by Dynamat.It cost less too.This stuff works awsome.If you order some it takes a few day to get there....these people are in Canada but well worth the wait.

Looks like a good product Tom. And you're right, it's a lot less expensive.

Take a look here......

Under "Adhesive-Back Damping Sheets" - "
3-Ply Aluminum" is basically the same specs, but even cheaper.

Also look at this stuff: http://www.raamaudio.com/
the slightly cheesy website belies the fact that the Raamat product is very good indeed. I have Brown Bread and Raamat and prefer the latter, although they are both very good. The guy who seels the Raamat is very good to deal with too.
Dynamat is far too expensive. If you visit any car audio boards where people use this stuff a lot, you'll find the Raamat and Brown Bread names coming up a lot.

Man, it's great to hear about this. I have spent the last year trying to find a good product to deaden the sound and Dynamat was just too expensive. Thanks guy's.

I did a bunch of reading around on this earlier in the year after asking here and getting no feedback. The car audio boards are the place to look. They are full of the wiggedy-wack, baggy pants brigade but they do know a bit about this stuff. I managed to chat with a couple of installers and got a few pointers along the way. The best way to use this stuff on floors is really with layers of the Brown Bread/Raamat/Dynamat whatever on the sheetmetal and then layers of insulating foam on top. The mat is a deadener not primarily a soundproofing material. The foam is there to absorb sound.
Gene - gheatley has posted on here about using this combination quite recently. Foam with a combination of closed and open cells is supposed to be the best. Rick at RaamAudio recommended 1/4" or 1/2" Insulite foam from Keyston.Bros. http://www.keystonbros.com/index2.html

Also if you are looking for foam try the place ken/klarue mentioned - McMaster-Carr. They have lots of different types.I like the look of the Adhesive Based Foam #8614K61. Search for that number and you can look at the catalogue page.
Here are a couple more links you might find useful:
General tips: http://www.resnet.wm.edu/~bplesn/sounddead.html http://www.math.ohio-state.edu/~ccun...xima/damp.html

Cascade. Good stuff but a bit more pricey than Raam/B-quiet stuff. http://www.mmxpress.com/cascade/cascade.htm http://www.cascadeaudio.com/

Ah, er....well, I think we started this thread with heat reduction and not necessarily sound insulation, but the information is great!

The Super dynamat keeps heat down better than any other products that I have seen or tested. The others may be more accoustically productive, but you will sweat to the oldies with out a dense heat reflective barrier. I do agree that some of the others are better sound dampners etc.

BTW, buy the Dynamat from Summit Racing or Jegs...the best prices there.

I like some of the other adheasive foam products that were pointed out. I use cheap carpet foam insulation, and I think I will try some other products even tho they will be far more expensive than what I am doing now.

Ok, getting back on topic a bit more, both the Brown Bread and Raamat products have an Aluminium layer like the Dynamat Super and Extreme and should act in like fashion. B-quiet have just started selling a product called Hliner which is sold as a heat shield layer. I think Cascade make something similar too.
theres also this stuff, but I've no idea how much it costs: http://www.quietride.com/heat_sheild.html
