seems to me that if this really were a low cost way to efficient power, the
factory would have done this.  HOWEVER--just saw a post in the P-car list
that the 951 (944 Turbo) exhaust header is double-walled stainless steel, and
ceramic coated.  i think this is telling us something here...(beyond that the
factory has lots of R&D $ and experience)

just a few more pennies
