Help, car is destroying o2's
 

In the last month I've gotten SES lights telling my that bank 2 sensor 1 is out. I replaced it the first time and the light went out for about 3-4 weeks. I went and got a new one from warranty today but I think I'm starting to piss them off haha.

It came on today and the same code came up. I'll get it when I go to break but I think it was one saying it was getting low voltage.

Could this be a computer issue? I don't see o2 sensors goin out like that.The car is catless but I don't see how that can make them go bad. Seeing how it was before the cat any way.

Headers.????

Yeah the car has pacesetter long tubes. It ran great for about 2 months. Then about 3 weeks ago the first o2 went out and it did it again today.
