Has anyone actually wrapped (direct contact) this product around an exhaust header? If so, your experience & assessment would be much appreciated. thx

It says in the description that it’s rated to 2000°F RADIANT heat and 300°F direct contact so unless you have a wet exhaust on your vehicle, I’d just stick to header wrap. It’s cheaper anyway

Can I use this to wrap a leaking muffler?

No. Muffler has comes out at pressure. Look at the products website and it well tell you for sure. If it doesn't say you can't, it doesn't mean you can

Can this be used to cover a hot air heating vent? I want to prevent the hot air from entering into rooms.

by itself I would think the adhesive side wouldn't last too long against the air flow. Now if you paste it on some board that you then screw on top of the vent, I don't see why not. Just a guess for what that's worth.

How thick is the material?

Once peeled and pasted, it is maybe the thickness of say, an average envelope with one single letter size paper folded in 3 inside, give or take. It isn't very thick but it seems to do the job and even pasted upside down (in my case on the outside bottom of my saddlebag an inch over my exhaust pipe) it holds very nicely. Mine has been there for now six months and 5,000 miles with a few biblical rain storms. Good stuff.
