To me if you are getting a DP you should be running either legit tune, which will take away check engine or JB4, which also will clear it.... the catalyst doesn't cost that much....
The problem is any tune that suppresses the rear o2's also won't allow the vehicle to pass emissions in most places. A pipe that allows a flash back to stock seems worth it to me to not have to swap to factory every year or two.
