Exhaust pipe heat shields?

As those of us with exMoD diesels know, the floor gets hot.

I'm considering these exhaust pipe heat shields from the exhaust manifold to the muffler.

Anyone else tried these?

I'm also considering some of this stuck to the bottom of the floorboard and on the bulkhead above the exhaust. (Yes, I've read the postings about sticking things to Rover parts exposed to water.)

Thoughts pro or con?

Mike

I put dynamat underneath my front floor boards, bulkhead I could reach with the engine in, seat box, transmission tunnel cover, and used this stuff

to "seal" all the panels when I put it back together and had a dramatic reduction in heat (I can wear flip flops now). Noise was reduced as well. I doubled up the dynamat on the transmission tunnel. So far no issues as for durability. Did a 2000 mile drive to, through, and home from Death Valley, some other trips involving water crossings and usual rain. I have a diesel as well.

Thanks Chris.

Just to be clear, you removed the floor panels to put that weatherstrip in?

Do you have some pictures of your Dynamat installation?

I installed the Thermo-Tec wrap on my ex-MOD 110. I felt like it helped but I made the problem worse by installing an automatic.
I intend to use Lizard-Skin & the dyna-mat type product soon.

Mike,

Yes, removed the floor panels and trans cover and lined the dynamat that way. Then when I reassembled I laid down the weatherstrip around the overlap and put the bolts right through it. It's like putty, never dries or cracks, waterproof, prevents water ingress. Had to order it on amazon but it's cheap, less than a tenner if I remember correctly. It can also be reused, so if I pull the floor panels I can reuse it. I think I went 3 beads wide. I didn't take pics but I will see what shots I can get tomorrow. To be complete I also dynamated the roof above the front seats, inside the passenger seat compartment, the access panels on the seat box and as many places as I could reach on the bulkhead, focusing on the footwell behind the turbo (I don't have a heat shield there. Used to run 150-190 degrees on my toes according to IR temp gun, haven't compared the after temps but after a 9 hour drive I didn't feel any heat on my feet). I still want to do the rear floor (I didn't do it when the internal cage was out so now I will have to piece it together around the drive train, such a dummy), the hood/bonnet, and sound insulation for the doors. I am very pleased with the heat reduction and satisfied with the sound reduction. I chose to do it this way because I didn't want to stick anything on my original sand glow .

Mike and Chris, thanks.

I have a soft top so I don't think I'll do the roof.

Anyone else have any experience with Dynamat or similar holding up on the underside of the vehicle? I like the idea of under as opposed to inside if I can help it. Looking for ideas for when the diesel goes in.

IMHO Dynamat is really the wrong choice for noiseproofing, especially against something like engine noise/diesel clatter.
