If its a heater code then you should be fine by replacing the sensor. I imagine who ever installed your test pipes used impact gun. Close enough vibration from the impact gun will damage the sensor! Thats why its not recommended to use impact on any exhaust work. Ask how I know :roll eyes: GL

Chances are that when they removed the old cat's. They used an air impact gun on the bolts. IF they did not remove the the O2 sensors before using the air imact gun. The vibrations from the gun WILL damage the O2 sensors. The first thing you do is to remove the sensors. The last thing you do is install the sensors. So many people here on the forum have run into the same problem with the sensors. Nobody learns.

I had a friend do it after hours at the performance shop he works at. Not sure what he used but I'm guessing it was impact gun that did it then. I never came across that problem in my reading, otherwise I would have mentioned it to him. Whatevs, $80 part and he's putting it in for free. Live and you learn.
