K I went to autozone and it is a P0420

Troubleshooting P0420
The PMC has determined that the catalyst system efficiency for the bank 1 is below threshold for the current engine operating conditions. (bank 1 identifies the location of cylinder #1, while bank 2 identifies the cylinders on the opposite bank)

Now that is cuz of the new headers? And if so how and where do I go about getting it fixed?
