I would agree with this. Slowing the airflow will likely raise the temp
quite a bit. When the airflow is turned down, it is still very very
hot.
But, while in my plane I can say there is more than enough heat
available, I don't know anymore if this is universal. There are now
planes flying with the Forsling exhaust instead of the standard
Vetterman, and I know at least one of those guys is struggling to
keep the heat coming out. Not sure if it's the heat muff style
or something else, but it's just that we now need more reports
from people with other various systems before you can know that
every one has the same heating performance.

Interestingly enough, it may actually, by decreasing the flow, increase the
temp of the air that's actually coming out back there. I'm just surmising
here, but if you restrict the velocity going from 2" to 1", the air may have
more time to be heated by the pipes...you'll have to let me know. When's
that bird gonna fly?

We have the Forsling exhaust.
Two heat muffs & just about the right amount of heat for NZ. Have to
turn the rear ones on at 9000ft & higher.
Otherwise, for local low level stuff we pretty much have the rear &
fronts off for most of the time.
No complaints at all about Forsling exhausts, and they sound really
great!

I found a simple solution to mine.
Took one of the Vetterman muffs off, and only use one to feed to the
firewall valve.
Can still select front, rear or both and it worked fine this winter
(once I insulated the baggage compartment bulkhead).
