Catalyst under effeciency
Yearly inspection is going around also need to renew registration, double whammy. got these DTC's from my Solus edge
[P200B] P0422 The efficiency of the right catalytic converter is insufficient. (function chain)
[P207E] P0432 The efficiency of the left catalytic converter is insufficient. (function chain)
any help is very appreciated! I'm tempted to believe its cause is from the muffler delete?
Mods: 76MM + belt wrap, Bosch 010, RaceIQ tune, Muffler delete, Lowering links. 99,5xx miles
