It's telling you there is too much oxygen in the exhaust or the output voltage is too low. Assuming is was OK before the headers, it's either not getting a good ground or the sensor isn't getting hot enough. The best bet is to replace it with a 4 wire sensor. One wire is a dedicated ground, two wires heat the sensor, the last is the sensor output.
