I was at SEMA and saw some insulation from Heatshield Products. https://www.summitracing.com/parts/hsp-170202 It is an aluminum backed insulation capable of handling 1800 degrees of continuous heat or 2200 degrees intermittent. Literature says it can be wrapped around headers. I was thinking this might be a good insulation solution to those Gen 5 owners with headers. We know the havoc that header heat can cause to surrounding parts. I held this product at SEMA and it seems like you could form it around the header and secure with a wire. It is very form-able. This wouldn't be a tight wrap around the header pipes like an exhaust wrap. They tell me because of this and the air gap that would exist it will not cause the headers to corrode prematurely.

I know that some of us were pushing a vendor on here to build mittens for the different brands of headers but that has really happened and even if they were available installation would require removal of the headers. This stuff should be able to be formed around the header and then secured. Should be straight forward. Coupled with some of their (or someone else's) spark plug boots it should protect pretty much everything under the hood. They also have Muffler Armor (which may actually be the same stuff but in different sizes) that can be wrapped around mufflers and even Catalytic Converters.

So has anyone tried this stuff?
