Okay... my two cents worth....  I've been building and running turbocharged cars
since the early 70's, and all with the exhaust wrapped.  Boost pressures in the
30-psi range.  These cars were drag raced, auto-x and hill climbed.  I never
replaced a down pipe because of the additional heat retained by the 
insulation...
period!!!  No rust thru, melting... or whatever else one might expect.
A possibility, perhaps... but not a probability!
S/S is the way to go, needles to say, but standard exhaust does work.
