the rotary engine by design needs to be rich at idle to run without misfiring. the converter needs to see 14.7 air fuel ratio to function correctly.
so thats the air pumps job, too add enough air into the exhaust to make the mixtures more "cat friendly".
the question is, is the metal cat robust enough to handle that? normal cats are not
