I did hear what sounded like some cleaning going on (likely the surface where the new equipment connects to the OEM header. Now whether they left those primary sensors on while they did that or not, I don't know. Either way they'll have to foot the bill.

Chances are that the O2 sensors are shot. A lot of times when someone works on the exhaust with an impact gun. About 80% of the time. The O2 sensors get damaged. The vibrations from the gun kills the sensors. For some reason the sensors on the Z are more sensitive to vibrations then others.
