I don't have Dyno data and I did not use a coating on my headers but I did
use wrap and I certainly noticed a tremendous difference in the decreased
amount of heat in the cockpit. So, even if it does not add HP but does make
the ride more comfortable while wearing our thick drivers suits it was
certainly worth the time that I spent carefully wrapping and spraying the
headers.
