has anyone used a exhaust wrap on the 'b' to keep the heat down in the engine bay, if so does it work. i used some on a westfield and was not sure if i got a lower temp, now i live in spain the air temp is in the summer around 30 so you need all the help you can get to keep cool

I have it on my manifold and downpipe. Engine bay temp is lower

may as well get the real thing, looks better too http://www.camcoat.u-net.com/Exhtprices2002.htm

Thats what I would do if i fitted a stainless manifold. no point having it done on the OEM manifold.

But that's just paint isnt it?? Not a heatshield??

The Camcoat answer, carried out for Aston Martin Lagonda and many successful race/rally teams and individuals, is to apply thin ceramic coatings to both the inside and outside of exhaust manifolds and pipe work. Turbochargers, Cats and silencers are coated externally.
Much more heat is now retained in the exhaust gases resulting in less heat radiation, more power and less noise.
