May have mentioned this before, but we wrap all of
the exhaust on Nascar and similar applications with
Thermo-Tec heat wrap.
It serves two purposes, keeps the heat in the pipes,
and avoids radiated heat to the driver.
I have even used it on turbochargers.

Archie,

 Some guys on the RV list have mentioned problems (thinning/wear on head
pipes and some blowouts) even on high quality stainless exhaust systems
when wrapped long term with this stuff. Have you had any of these types of
problems or is this not an issue on race cars due to frequent
removal/replacement/inspection/etc...? Do you have any experience with the
applied thermal barrier coatings such as Jet Hot, etc.. and can you
recommend them?
