Our Nascar and Busch GN engines have their exhausts thermal
wrapped. This does two things, Keeps heat in the pipes, and
reduces radiated heat to the driver from firewall and floor.
There is, however a small drawback. When uncoated mild steel
is used, condensation forms between the wrap and the pipe.
This is not an issue with most of these cars, however, due to
the frequency of replacement or repair.
Effective as the thermal wrap may be, it may be an issue
with the use of uncoated mild steel.

Do the NASCAR guys use red RTV along with the wrap Archie?
