Another persistent P0420

Curious as well. My CEL came back on after a few hundred miles but was able to get inspection so not in a rush.

It probably helped kick the can down the road.

I'm running Magnaflow's cats and y-pipe, 51578, on mine since 2018 from Got Exhaust, a vendor here, though I haven't heard from them in a while. Just over 49K miles now, no issues.

Hi, sorry for the delayed reply. I don’t get notifications for whatever reason.

No check engine light, no issues so far after a few thousand miles.
