I have the Vetterman crossover exhaust with mufflers and one heat muff on the right muffler. My Rv9A has an 0-320 E3D 150 HP engine.I flew for the first time in below freezing weather recently and just wanted to give a Pirep. I only had to barely crack open the cabin heat vent to warm things up quickly. Full open puts out tons of heat. I was concerned about my wife getting cold traveling but not any more. This setup is awesome. Thanks Larry.
