N611GB turbo headers are wrapped in the fiberglass wrap in only a few places where the hot exhaust pipes come close to (hard) oil lines and oil filter. Later more sections may be wrapped if heating the cowl or other parts becomes a problem.
There is doubt that it'll do any good as the flowing oil in those parts should cool them. These parts of the oil filter & cooler lines are hard and at the input to the cooler, so the oil will just go in there and get cooled anyway. The cooler is oversized 8.5x11in. jg
