help getting DTC: 16815 (P0431) Warm up catalyst efficiency below treshold Bank 2
I thought AWE downpipes were not suppose to throw codes? Or could this be related to something else?

info...
you are correct this should not happen w the AWE cats but, this code can also be caused by a faulty O2 sensor(secondary usually) or high octane fuel(slower light off cooler idle egt)! try resetting the code if it happens again call AWE the beauty of the AWE pipes is that in rare instances such as this you do not have to remove the entire downpipe to get a cat fixed! anyway i highly doubt it's a cat problem cause I use the same co's cats and mine have seen some pretty crazy air fuels and flows and still going strong!
