Isn't there some cable you have to get to clear the light on new ages after you fit a downpipe
But maybe it can be cleared for good when mapping without it
its normal keith its because the rear oxygen sensor is too hot due to no cat fitted get the mapper to turn it off or raise temp threshold of the sensor
iv used similar things to below and they do work but your mapping so no need
