Question is if a "medium-lvl" CAT + spacer is enough to prevent enrichment. "Medium-level" cat being like a Milltek sport or Wagner, which are both EU6, but can be hit or miss with CELs. I know that combo would keep the CEL off; I don't know if it maintains AFR.What’s the question? The CEL is due to cat not being efficient enough. The unplugging of the rear o2 was to prevent the enrichment but unplugging it makes the ECU unhappy so it triggers a CEL. Cobb can no longer turn off the CEL due to EPA crackdown so your best bet is to get a DP with a good cat and cross your fingers. Or dont run cobb…..
Trying to avoid the EPA GESI tax if possible. I have emissions testing, but they're primarily concerned with readiness/CEL. If I have to bite the bullet on a GESI dp, I will, but
