Would this be suitable for exhaust headers on a V8 engine?

You could try although I'm sure it wasn't designed for that purpose.
Brilliant. Needed some fire cement. Ordered.

May crumble under vibration? I dont know just speculating.... given the effort of changing it if it does, probably not worth the saving.
Thanks op.

I've tried using fire cement (not this brand though) on exhausts and the problem was that many of them go hard and brittle when exposed to heat and then they crumble under vibration and fall out of the joint, as greenfinger suggests above.
The way to find out is to squeeze some onto the header, run the engine up to temperature and see what happens to it, see if it can tolerate any movement and if it stays stuck to the metal. If not then don't bother.

Just been in Halifax, they have a few - around 6 (which is more than their website shows)
They also had one tube of own brand acrylic sealant for £1, which was more what I wanted so went for that
Thanks OP

This is a construction product, indeed it will split at a certain temperature or due to vibration but will have served (hopefully) its purpose of occupant and/or building protection, i.e. escape time or firefighter arrival time (sacrificial).
