Greg, did this exhaust guy elaborate on why = it might not be a good idea?

Why can=E2=80=99t we move the heat muff furt= her from engine to where temps are similar to Lycoming =E2=80=93 use flex-s= tainless tubing for ducting?

Jeff,

I'm considering going to a heat muff since t= here is sooooooo much exhaust heat that's just going to waste.  I was = going to incorporate it into the heat shield of my newest muffler design.&n= bsp; Of course, I'll need to add a CO detector in the cabin for safety.
