Exhaust Wrap on an NA car?
 

dumb tech question of the week from me ..

Would wrapping headers on a naturally aspirated car help any? I know of 2 rally competitors that have done that :?: but i can't figure out why .

If it was helpful i'de expect to see most of the NA cars doing it ...


:?:

All it does for you is keep a little bit of heat out of the engine bay. Especially with cast manifolds, there is no performance advantage.

It help protect your hand from burning when you need to fix something close to the exhaust.
