Last trip to Moab almost melted the kids crayons in the back of Suzi. Seems like big nasty muffler generates quite a bit of heat back there. This looks pretty good. Thoughts?

NASA uses it, so it must be good...
Something I might consider for the firewall..

Howard,
"Cheapest" would be to just get a piece of household fiberglass insulation from the Big Boxes. Its very light. Have wifey sow a big fabric "pillowcase" in something that matches your interior and you'd have a nice big soft cushy and cool rear trunk for a few bucks....
If you are trying to deaden sound, then this adhesive backed stuck-on foam with lead liner is the way to go.. but you pay weight penalty:

Keeps my diesels' noise in the engine room...

Just bite the bullet and go for the 24K gold foil. You know you want it...

Do you have a muffler shield?
Where would you put it? Underneath correct?

What's a muffler shield? Was just going to line the trunk, but will take a look underneath. Sounds like a good idea if it doesn't trap water.

They sell the same stuff for boat cowels in marine stores but it is a little heavy.
I don't see how driving with your roof off makes for a hot interior though? If the paint dosen't peal, it ain't that hot!

Howard,
You can easily slap together a heat shield. Go to Big Box or Orchard Supply, and buy a piece of aluminum sheet metal. Clamp it between 2 2"x4"s, bend it to suit, and pop a couple of screw mounting holes in it...

Sounds like a good project. This was first long trip with the Triad, and it got a bit toasty back there. Was a shield stock on 914's?
Posted by: BMartin914 Oct 14 2006, 12:14 PM
All I've worked on have had it.

Mine's also not shielded. But there was previous rust repair from in the rear trunk in my car...

late cars were all welded on
