So I installed SP long tube headers with hi-flow cats on my own ( I have 0 mechanical experience) and honestly the installation wasn't terrible the worst part was getting the O2 sensors unplugged and unscrewed. After the install I got a check engine light and all codes were about the O2 sensors. Now I was told this would happen and I planned/plan on getting a tune, but right now I just don't have the money set aside. I was looking at getting O2 spacers or the mini cat adapters to get rid of the permanent codes but when I finally started reading into the codes, I am unsure if the codes are from the headers or if I broke the O2 sensors after install or I plugged them in wrong with the extension cables or something.

The codes I'm getting are as follows: P0030, P0031, P00132, P00135, P069E

P0030 is the heater control circuit in bank 1 sensor 1
P0031 is low voltage in sensor 1
P0132 is high voltage sensor 1
P0135 is heater performance sensor 1


I would appreciate any feedback as I am really at a loss for what to do next to fix this problem. Thank you!

I could be wrong but I think those codes have to be tuned out, or in some way adjusted at the very minimum.

I think this is correct.
I would say immediate concern is for OP to make sure wiring harnesses are well away from the headers. Since he claims limited mechanical experience, he should be aware that the biggest problem with headers is melting insulation. That can result in codes and problems that can't be "tuned out."

Yes, I was aware that this could happen, so I made sure wiring harnesses were well run along where insulation would not get melted

No, you shouldn't have to mess with the front sensors in the tune. I would disconnect the drivers side front sensor and double check that the pins are seated correctly and that a wire hasn't been damaged. If that checks out ok, then you may need to replace that sensor. If they are the original sensors they are probably at the end of their life anyway.

Did you use the special socket with the slit? I have not removed the sensor on this car, but others I have always used the special socket to avoid damaging the wires.
This set even comes with a thread chaser. I did not know it was common for these threads to get damaged. But I guess if they are rusted in it's the same as spark plugs. Maybe use anti-seize when reinstalling.
