@Superdannyboy has a CEL from the catted version. I have seen other posts where it has happened for other folks. I think I remember reading that the middle insert is best for the CVF catted downpipe.@Superdannyboy - My friend uses the smallest insert. But to clarify this is only needed for catless downpipes.
Your downpipe is catted so should pass inspection as I would think the catted downpipe doesnt cause a CEL. Also, I’ve never seen an inspection failed for the presence of an aftermarket cat.
