Welcome to just answer.
My name is***** try to assist you here.
Both codes refer to bank 1 O2 sensor, one refers to mixture monitoring, the other is the heated circuit of the sensor.
It would seem the sensor may be damaged, but it's worth checking the connections as they may have been disturbed whilst changing the exhaust.
Hope this helps, if you need more info, please let me know.

As the v6 is mounted transversely which is the bank 1 is it the front or rear bank
UK Auto Mechanic: Trevor, UK Car Mechanic replied 3 years ago
Hi
Bank 1 is the left hand side as you look from the front of the engine (not the front of the vehicle).
