Those of you that are flying, how did you approach this item. It seems to me that with all that heat going out the tailpipe, it is a no-brainer... except for the carbon-monoxide thing. Then again, I don't want to be scalded with hot ethylene-glycol either. The exhaust muff seems like the lighter and simpler solution. On the other hand, with proper ducting, the heater core could add extra cooling during climb-out. Comments welcome, Mark S. (hot oil exchanger is out of the question)
