This, in combo with Denso downstream o2 sensor, resulted in no codes after clearing them and doing multiple start up cycles. Car isn’t registered yet, so don’t know yet after long drive. Thread started to have a single location for working after market cats listed.
Easy peasy, Just put a cat converter shield over a non carb complainant cat and you’ll pass visual inspections.
