Help with O2 Sensor Error Codes

Hello,

After I installed my VRSF downpipes I constantly get a SES light for o2 sensor related errors, anyone have any idea why this might be? I attached a screenshot of the jb4 app for the codes, though this happened before the jb4 was installed as well. I've had the downpipes for about 4 months and the jb4 for two.

I did go through and made sure I didn't install any o2 sensors backwards.
