Need some CEL code info.
OK...This is the code I pulled from my 00 RS with a ProECM, MRT header back, and Cobb Intake.
P0136 - O2 sensor Circuit malfunction bank 1 sensor 2.
Freeze frame data
Fuel System 1 - Closed Loop
Fuel system 2 - not supported
Load value - 18.8%
Coolant temp - 181F
Short term fuel trim 1 - 1.5%
Long term fuel trim 1 - 4.6%
Map sensor - 14 in.hg
Engine RPM - 2827rpm
Vehicle speed - 44mph
Now I was expecting a cat efficiency code, becuase of my header, but got this instead. So.......what does it mean?

I'd say clear it, and see if it comes back.
If it follows you home again, might be worth purchasing a new O2 sensor.
Only thing I can think of might be something with the wires, or maybe how it's connected to the ECU. If it's a "circuit" malfunction, it might not be the sensor itself, but it's hard to say. Check your wiring (if you've touched it at all before) and make sure the sensor is still securely plugged in. Otherwise, I'm outta ideas.

well either your A/F sensor is screwed or you are losing too much heat thru the headers and it should read slow response.
