First off a catted DP or non catted DP you will still fail emissions. Unless your state does not do a visual check, but I see you live in Cali, so you FAIL. Got to love California.
If you get a AP stage 2 it will eliminate the CEL codes for the DP. If not you will have to do the mechanical fix or use the resistor.
Other then that have fun breaking the law. I will be there soon, hopefully.
