2000 Integra R

I got a code 63 after header, highflow cat, and exhaust install.(2.5 all the way) is this O2 sensor even related to the header and cat sensor or is this code talking about a completly different sensor.

code 63 Oxygen Sensor, Heated - Sensor 2 (Secondary) high voltage, low voltage, or slow response

I need some remedy/cure. Thanks
