What does heat wrapping actually do? You say that's your DP you just wrapped, as in the DP leading to your exhaust which then exits the car via the tail pipes...why would you do it there ?

Quoted from a quick google search:
Exhaust wrap maintains hotter exhaust and header gases, decreases the gas density, and that allows the exhaust gas to exit the system faster! This increases exhaust scavenging, pulling intake and exhaust gases through the system faster, helping to lower intake temperatures: that equals more horsepower. Premium exhaust wrap also reduces radiant heat damage and can lower under hood temperatures by as much as 60%. Lower overall under hood temperatures can further reduce your intake temperatures.
If you can believe that word for word
