o2 sensor question

[flyboi001]

If I run 2.5'' pipe with headers and will it make the o2 sensors fail and turn on the check engine light? And if so will I lose power. does anyone know where I can get the adapters to fool the sensors??

Changing the pipe size won't kill the O2 sensors.

Leaded fuel and age kill the O2 sensors.

Yes, with no o2's on the stock ecu you will use more fuel.
