With plugs up, the headers exit to the rear and the ends are capped off. It appears that the last 4 inches of the pipes have 1/2" holes drilled in the sides of the pipes and a common shroud of oval shape is covering the holes at approximately 1/2" clearance from the pipes. It is stated that this works well. Is anyone familiar with this aircraft. If it works it sure is simple. I pulled the engine tonight to rework the engine mount to install the oil cooler like Jim Weir has his installed. I hope we are having fun and this project will bark by the end of January.
