I've seen people use header wraps to insulate their headers to keep the heat inside which supposedly helps speed the exhaust through the system and also potentially helps reduce engine compartment temperature. Has anybody messed with this seemingly simple upgrade and if so was it helpful in any way? Also, if there is a real world benefit, does it apply with a stock 996 exhaust/engine?

I replied in the other thread for you.

 

Jet Hot ceramic coatings is another alternative to wrapping. Check out their website.
