Exhaust heat shield
My W463 300 SWB has a stainless exhaust which was fitted some time ago. There is an existing heat shied but there is a section of the exhaust which runs fairly close to the bulkhead in the drivers footwell (just above the pedals) and this section of the footwell gets REALLY hot. You'd burn your fingers if you tried to touch it after a bit of a run.
My question is, has anyone any experience of adhesive material heat shields such as

Do they work?
Being adhesive - how long are they likely to stay stuck to the underneath of a G Wagon in a very HOT and sometimes wet environment?
Any other recommendations?

don't know if info any use but on the Harley
we use strips of fire blanket type stuff wrap around the exhaust fix with stainless steel wire
can get from any hot rod / speed shop
mark pop in to shaws harley Davidson at the end of your road and ASK
Mark, my 280GE has a rectangular piece of whitish fibreglass type material (bit like a blanket) wedged behind pipe between bulkhead.
But I plan to remove the current badly fitted pipe and renew so will also address this blanket at the same time.
Yes buddy I do mean Wedged ! But having said that I have not as yet made any efforts to remove or free it but it does appear to me that if you pulled it it would just come out.
Looks like it was put there and the exhaust was fitted and it is simply the pipe itself which is keeping it in place.
I do need to get a new pipe but currently finance is restricted and i've already performed a few repairs and sourced many parts so the pipes needs wait just a while.
BUT heat is not an issue within the cabin or floorpan so the blanket is working ok.
The original heatshields on early 463 s were made of a fibre material, covered with a thin aluminium foil, and were not very durable. New replacements from MB are available as all metal, but cost around £90 for the down pipe shield and similar amount for the one above the catalytic converter section. The whole section from just below the brake servo to the end of the catalytic converter should be protected by 2 overlapping shields.
You could, however, make your own from thin aluminium sheet.
Alternatively, you might try to wrap the pipes with glass-fibre bandaging for exhausts (secured at each end with jubilee clips), which will limit heat transfer, and actually improve engine efficiency a little.

Hi Neil,
When you say "wedged", do you really mean "wedged" as in just stuffed in the gap rather than attached to the bulkhead or exhaust in some more permanent way?
