Wrapped Headers

[JMF]

What is the benefit of having wrapped headers ? Also what is the material made of ? Thanks

Benefit is aislate for hot under hood and more air fresh in the air filter.
Cons is a wraped mantains moisuture and some headers deteriorates prematurely.
Some headers vendor not recommended wraped

Also supposed to be some performance benefit to keeping the heat up in the headers I believe.

  what the other Guys say    , wrapping headers causes them to rot / rust quicker no matter what coating is put on them ,  ok for a race car that's being constantly taken apart etc ,  no good for a daily ! shame though good idea

Worse case scenario:  they become oil soaked, then catch fire.   I've never seen it happen, but have heard that it could

Hadda set wrapped on a Duster drag car. Unwrapped to re-wrap and headers had crystallized. Hit with hammer and might as well been made of glass. Wrap em if you like....
