I'm looking to install a second heat muff on my RV6A to increase the cabin heat. I live in the north and fly in the dead of winter. The current system with one muff is not sufficient and one of my worst flights involved me drinking out of a water bottle that had significant ice in it which formed during my 2 hour flight. In order to maximize heat gained in the cabin I'm wondering if it would be better to add a second air intake and make the second muff on a completely separate set of tubing all the way to the cabin OR if I should place a Y intersection (can be seen in the link below) just after the existing air intake before the existing heat muff and have one intake serving two heat muffs.

My theory is that I should have a second air intake because of the following. With the Y I would expect the incoming air volume to remain the same but the outgoing air to be hotter than it currently is due to the slower velocity through the muff. However as the air increases in temperature, it heats slower and thus I think the higher volume of cooler heat would effectively dump more joules of energy into the cabin and thus heat the cabin up better.
However, I believe (but don't know) that the exhaust temperature is in the thousands of degrees fahrenheit (is that number crazy?). If that is so, the decrease in heat transfer speed due to the warming of the intake air would be negligible since there is still a very large difference between a thousand and a hundred degrees. The Y would be a heck of a lot easier to install as well since I wouldn't need to create a new intake hole.
Thoughts? Suggestions?
