Be advised that the adhesive is only good for 500 degrees. It melts so you really need to pin it in place after you mount it with sheet metal screws or pop rivets if it is right up against the exhausts.
Good ceramic coatings on the headers, double coated, inside and outside of the tube will bring the header temps down.
