I still dont understand how you’re getting a code for the secondary cat when theres no O2 sensor downstream of that cat. But theres a lot of things I dont understand. Hope the light stays off.

when unmonitered downstream cats fail they overload the monitered upstream cats. Often times all will have to be replaced to get rid of the code permanently.

Passed emissions! Good for a while at least, haha. Hopefully the magnaflow cat holds up.

That's absolutely true but the unmonitored down stream cats have absolutely no affect on the first set of monitored cats.
