<VV> Re: [fastvair] Wrapping turbo pipes

The issue isn't one of salt corrosion or moisture really... The basic 
elcheapo mild steel metallurgy will not hold up to the temperature.  I 
agree with Mike Mann. Coat the pipes, but do not wrap them (unless this 
is an all-out track car where you are willing to replace pipes very 
regularly).   The aluminization is worthless for protection for the 
temperatures we are talking about!  Matt was spot on with regard to SS 
exhaust.  If you want a super insulated exhaust to last, have it custom 
made out of 300 series SS.
