So it could have something to do with having a fully catLESS exhaust system w/ full functional o2 sensors

It's an EGT code, nothing to do with the 02 sensors. Check the EGT probe if you still have one, also check the wiring harness to the probe for damage. Sometimes the harness contacts the exhaust and melts.

Catless uppipe? Search for 2.2kohm resistor.

Agree with Mulder, nothing to do with O2 sensors.

Uppipe, as stated this code has nothing to do with the 02's or downpipe.
