please advise

Ok P2096 is not normal and not good

The code you might throw running anything but stock header on stage1 tune is P0420 cat efficiency and is easly disabled in tune using romraider.
P2096 indicated a serious fueling problem in that the fuel trims have maxed out (40% adjustment) and the ecu is still not getting the correct afr.
As you have jist installed header its most likely a exhaust leak or damaged 02sensor.
or you put the 02 spacer on the front sensor.
if you have access to tune you dont need any spacers and they should always go on rear sensor after cat, but remove any spacer .
log the tune you will liky see very high ltft and lean afr, this is most likely due to your o2 spacer being on front sensor of exhaust leak or damaged sensor or sensors plugged into wrong socket black to black and grey to grey the grey sensor plug is for front sensor
