I agree with your observation. I unhooked mine; but it didn't seem to
make any difference in the
cabin temp so put it back after several hours of flying. Wrapping the
cabin air scat tube with
fireproof insulation made the cabin air cooler.

My heat box leaks, so in the summer I remove the tubing from the
heat exchanger to the heat box. I was thinking about using a plug
on the hole in the baffling that supplies the ram air to the cabin
heat. This would stop the heat coming into the cabin and also aid
in cooling the engine. I haven't done that yet because I have
heard the same thing that Ed stated above. But when you think
about it, it is no different than flying with the cabin heat turned
off. That part of the exhaust pipe is not receiving any airflow at
that time.
Just my thoughts.
Have anyone ever seen the exhaust pipe inside a heat baffle melt on
an airplane?

Also, be aware that a lot of owners remove the cabin heat scat hose
from the muff to the firewall during the summer. This reduces the
blast of hot air on the flapper box and firewall. Since some
flapper boxes leak, this keeps the cabin cooler in the summer.

Don’t forget to reinstall it in the fall.
