Unhappy P2271 Error Code

Hello everyone! I am new here but I am having issues with my O2 sensors on my 11 Challenger RT, it has an aftermarket exhaust on it and the engine light keeps flashing with the aforementioned error code. Anyone have similar issues and can suggest a fix?

Try replacing the sensor.

Yeah, that is what I am trying to do, know where I can find replacement OEM sensors or a reputable manufacturer? A coworker suggested NTK
