I had bad cooling problems on my 80hp Classic until I removed the second muffler and replaced it with a straight pipe.
Now, while it makes more noise, I can climb forever at 85kt in the Florida summer: 30C (at)1000ft on a relatively cool morning.
That chamber of the muffler blocks a lot of air.

Subject: Classic firewall.... singleton vs steel & cooling.
Hi folks,
I found on my classic that the composite firewall pretty well closed off the cowl
exit on my classic, with the muffler tucked up right against it.
I now wonder if the rudder pedal tubes and drive arms can be left on the engine
side of the firewall, and simply fabricate a stainless firewall sheet in line
with the upper firewall, leaving the rudder pedals, and all four engine mounts
on the engine side of the firewall.
I wonder how warm the pedals will get in the summer? My classic does have nicely
overlapping and tight stainless rudder pedal passthroughs.
Does anyone out there have a classic with a firewall as i have described?
Cheers and thx,
Pete

I have a set up (the standard set up) much the same as your proposal.
The rudder pedals don't get hot.
Anything in the tunnel behind the steel firewall gets really hot, unless you have
a monowheel with lots of default circulating cooling air. Accordingly, I have
a 'fireblanket' on the back side of the steel, which reduces temperatures in
the tunnel.
