Thoughts on exhaust heat wrap?

[Metalman]

My car is going in to have the exhaust system tweaked in a couple of weeks and I'm getting them to replace the old brittle heat wrap while they're at it. Can anyone tell me how much I need to wrap a twin system, I was thinking about 60m? Also what brands have you guys used, I know DEI is supposed to be the dogs nuts but it's £180 for two 30m rolls! I have found magmawrap on ebay and it's rated for the same temps as the DEI stuff, anyone know if it's any good? And lastly, when I spoke to Dave at jetstream I'm sure he told me to remove the wrap I have on the manifolds as they can get too hot and crack, am I right in thinking this? Thanks guys.

Mine is wrapped from the manifold to the silencers, including turbo blankets. I think I'll remove the wrap on the manifolds but have the rest covered, I just hope I'm not going to need a new pair of manifolds.

Had a look on merlin motorsport, looks like the stuff you used has an even higher rating tux so that could be the way to go if yours is still on there ok.
Think I'll remove the turbo blankets as well, I suppose keeping all that heat in the turbo can't do it any good but surely wrapping the silencers is a good idea to keep heat away from the intercooler housing?

Thanks guys some great info, at least I have some brand names to look into and my decision on using dei has just been made easier! I think I may give the magmawrap a try, it's a good price and the dealer seems to think it's up to the job. I've used some nimbus heat shielding before which was good so will also look into that.
