You need a tune.

...and hopefully he resides in a state that doesn't care if he removes federally mandated emissions equipment.

Get a tune such as blackbear to have them "tuned out". Or either pay to get some new ones welded on. Either way its gonna cost yah some $$$$.

 

Why did you get them cut off out of curiosity ?

Ask the gm technician

Running rich is unlikely related to the missing cats.

Correct me if I'm wrong but running rich would be the first set of 02 sensors. The second set should merely read catalyst efficiency low if the cats are removed

You get a cookie!

 

PO4030 is NOT a rich code, it is a catalyst efficiency code out of range. Since the cats are gone you'll get that code all day long until tune out the post cat sensors, replace the cats, etc......
