I presume that you are asking about exhausts since stainless is not
used in most of GA aircraft at all.

*Correct me if I'm wrong, but are many firewalls not made of stainless, or
layers of stainless and other heat resistant fibers?

Most are stainless, as are the exhaust systems. Stainless is iron
with lots of chromium and nickel. Inconel, IIRC, is chromium and
copper, and Monel is chromium and nickel, no iron in either. That's
from memory, which is often unreliable now. Plain carbon steel mighht
be found in homebuilt exhaust systems, like mine, but their lives are
much shorter.
