Scott, (and everyone else)
	If we wrap or ceramic-coat the manifold/turbo/downpipe, wouldn't 
that make the exhaust flow hotter, increasing the velocity?  That 
is the primary reason for Stainless steel exhausts, and coated 
manifolds.  This extra velocity is what gives the increased 
performance.  If you have to increase the coolong capability after 
shutdown, well then taht is just the price of performance.
