It is actually illegal in California to delete the secondary cats, California is the whole reason the secondary cats are on the car. Up until 2008 GM made 2 versions of each vehicle, 49 state cars that didn't have secondary cats and a California certified vehicle that had the secondary cat. Then in 2009 GM switched over to save money for production costs and then only made a 50 state compliant vehicle.
