Wait - which catted headers? Aftermarket and do you have other intake/exhaust mods? If so, you're going to need to disable the DTC for the code you're getting (probably P0420). The catted aftermarket headers out there are designed to be CEL-free only with stock intake/exhaust. Make the system more free-flowing than that, and you need to do something about the O2 sensor.
