I've been driving the resto-modded 66 coupe the last couple days. The only thing inside upholstery wise is the driver seat. I've found that the driveshaft tunnel gets hot- not warm but hot. The dual exhaust was recently installed and runs down the tunnel-hence the heat. This restomod is also 350+ HP with 2 1/4" pipes. Is this normal and is not noticable once the complete interior is in?
Has anybody else noticed this before.

Even with insulation and carpet, the tunnel in mine gets pretty warm. It'll melt all the ice out of a drink in about 30 minutes! I would imagine that a bare tunnel would get hot.

I have a dynamat type product and insulation. Would you put the dynamat product down 1st. It seems like an asphalt type product.

Where can I get the dynamat product, and do you know how much it will cost me? I am having a similar issue.

Thanks,
Tosh

You can buy Dynamat without the printed logo at McMaster Carr. Search for part # 9709T19. It is $12.79 for a 32"x54" sheet. I used 5 sheets in my car (2 layers on the doors and 1 layer on all the floor boards). Then I covered it with 1/2 carpet jute from Home Depot. The car is much quiter now.

After I POR-15'd my floor, I used that aluminum/jute insulator/heat shield when I changed out my carpet. Then I put on that rubber/asphault insulator kit that lots of the Mustang shops sell over the top of it. It definitely cut out the heat and the interior noise dropped dramatically.

I agree with the dyno mat idea, that is what i am doing in my 65' fastback. Only i am using a diffrent product, it is called brown bread. I have read a few reviews in some car audio mags that show that this stuff is a little better than dynomat, and a whole lot cheaper! I will be doing my whole interior (firewall to taillights, doors everything) and figure it will only be about $200 - $300. Here is the web site:

Good luck and let us know how it turns out,
