I have enough insulation under the carpet that heat in the interior is not really a problem - but I'll be curious to see how that DEI insulation works as I may need to step up to it.

I can't imagine any coating holding up to that type of heat. I've used lizard skin on the interior of a mustang before, but I thought it was more for sound insulation, not heat.
Anyway, at least one of the muffler wraps should show up this week and I will post back with results once I have it or them installed. They are around $50.00 a piece, but well worth it if they actually reduce the heat. Im guessing overall I will have around $250.00 in insulation. Picture and link below.

No, it's a thermal insulator coating - supposed to be good for 500 degrees but I'm right at that threshold. Plus, I may not have been thorough enough with my surface prep before applying it. The mufflers with ceramic coating seem to act like a heat sink. Long after my headers and collector are cooling off the muffler temperatures stay up there. Doing it again, I think I wouldn't ceramic coat them.
