After replacing your catalytic converter you won't save anything.

On a modern car, you'll also wipe out the O2 sensor very quickly.

Back in the early 90s, I owned a Merc convertible with a high
compression 429ci V-8 that had to have at least 99 octane mogas to
avoid knocking. At the same time, I owned a '59 172 with an O-300
that absolutely hated being run on avgas. Lots of lead fouling and
gummed up valves. My solution turned out to be quite easy. I ran
the 172 on 87 octane unleaded car gas and the Merc ran 100LL avgas.
Both were quite happy with the change.

As for prices, yesterday I came up dead even. $2.12/gal for both
avgas and mid-grade car gas.
