A cross threaded and/or leaking O2 shouldn't show voltage too low. Cat inefficiency or too lean/rich, sure. So make sure they verify the sensors are plugged into the right plugs, and that the harness connectors are in good shape. This could be as simple as a poor connection.
Worst case, if the sensor was damaged from cross threading, the bung on the header might be too damaged to simply chase the threads again, and it might need a new bung welded on.

Oh God. I didn't know it was that expensive for a pair of O2 sensors. Should I take it back to nextmod and have them looked at it? Since they did do the install. And how do I go about getting a new bung for the openflashheaders? Jesus, this is giving me more problem than I thought.
