when you put the secondary cat by pass on did the CEL turn on?
Doubt you'd get a CEL with Cat bypass. Both O2 sensors are fore & aft of the primary Cat. There is no O2 sensor after the secondary Cat.

Cel

No.......the CEL does not come on with seconday cat delete. It only comes on if you replace the headers and do a complete cat delete. If you delete all the cats you will get a bad exhaust smell if the cabin in reverse and at stoplights. It do make more power though. P.S....Nice seats...........I've got seat envy.
