They should reimburse you for that sensor you did not need.

Well the high flow cat install could partially be to blame for the bad header sensor. Those sensors in the header are extremely sensitive and you can not use impact wrenches when doing the HFC install because the vibration could cause the sensor to go bad. Although sometimes you really have no choice because those top bolts on the cats are ridiculously overtorqued from the factory.
