Alan,
Many thanks -
I have the manifold already coated here locally, to send it back and forth
would be a bit of a pain. But I have coated ceramically headers on Volvos
with this company and they lasted very well..
Best, tadek

Tadek -
Having seen the work on your BN2, I would highly recommend going with the
Jet Hot coating from the US for your Exhaust Header. It will keep engine
temperature down substantially, and really make the car a nice one to drive
as far as you want in Europe without worrying about heat problems in the
engine bay. Again, a link to the header on my Atlantic, which still looks
exactly the same now as it did in the picture, even after a couple thousand
miles:

the bonnet. Very effective:

<http://www.jet-hot.com/> The Extreme Sterling is what you want, and it is
far more durable than old fashioned ceramic coatings. It's not too
expensive, the only thing is you have to remove all the studs and bolts from
your header before sending it.

Hello all,
I have done some research on this and I found that the heat wrap has 2
drawbacks:
- if you isolate your manifold and the down pipe continuously you may end
up with a burned pipe, as the heat that is traveling through the pipe has
nowhere to escape, in result heating the exhaust system to a point where it
may burn out. A solution is to wrap it intermittently, leaving gaps.
- the heat wrap (although flame retardant) may start burning.
Ceramic coating is better in both cases, although more expensive. Ceramic
coating may though look more original on your car if you choose the right
color..
There was an article comparing the two - I have it and will post as soon as
get back home.
With the heads we have, where exhaust & inlet are on the same side of the
engine I would not use heat wrap.
Best, Tadek
