the wrap itself shouldnt fall off if you put it on well and secure it well. it is a woven fiberglass fabric. if you burn through the wrap then you have more serious problems than the wrap to worry about.

the ceramic coating may crack. wrapping that would help I guess.

Possibly
I think it's probably wear and tear that breaks up the heat wrap...getting hit with rocks, sticks, tire pieces, getting soaked in water and then dried back out time and time again. The aluminum wrap should help protect the heat wrap from most of that stuff, possibly increasing the life of the wrap. I don't know for sure though, I've never done a side by side life expectancy test on heat wrap with and without aluminum wrap on top of it.

On my 6.6L nitrous durango, I wrapped both headers with the 2 2"x50' rolls Using metal ties. I learned a few important lessons from that build. Most important!---->Carry a fire extinguisher!!!!!!!!! My durango shot flames from under the hood at a stop light and I had no way to put it out(Pissing on it wouldn't of done ****). I never found what started the fire, but suspect that the passinger side fuel rail blew off spraying fuel everywhere.
For the short time I had it, the heat wrap worked very will. I'm sure that stuff works better than coatings. The aluminum tape looks cool and is very creative, but I would like to see how its durability ends up. All that adhesive may just melt or become brittle over time.
For my next exhaust setup I plan on doing this. First, wrapping with the 2 2"x50' rolls and securing with normal stainless steel ties. Then wrapping over that with the heat sheet wraping. Its a cloth that's woven on the inside and aluminum reflective on the outside. I have some made by DEI. Haven decided how I will secure that yet, but you can get it in tubing. I may just get tubing sheaths and cut down side and secure. It will defiantly hold inner wrapping together and be much more durable. Plus extra insulation. I'm not sure but think this is what NASA uses. If its what they use it's sure as **** good enough for me.8). Just my 2 c.

As I said before, it's been on my car for a year and a half and still looks and works like the first day I put it on. At one point a good 2 foot section of the header was literally coated with a few quarts of oil. When I got the mess cleaned up off the floor, I started up the car and drove around. After things got hot, the oil on the header smoked off, and that was the extent of it. A spill like that would have lit the car on fire if the wrap was exposed (it's happened on several occasions to other cars, apparently yours included).

Default pipe

I wrapped & painted the wrap on my PDE down pipe



deep snow took most of it off one winter





I didn't like what I found when I unwrapped what was left of the wrap looks like rust on stainless steel


I'm taking it with me to work at the body shop I plan to remove all rust & paint with high temperature paint then wrap again

The way the metal is discolored has me a little concerned

About how much of a spool time difference would there be between a header being wrapped and not being wrapped, same header, and everything else the same except for the wrap?
