If the great State of MD requires OBD testing you will have to go with the PPE catted DP in order to pass emissions testing,if your tuned make sure to revert back to stock tune a few days prior to testing in order to complete the full driving cycle in order to complete I/M readiness status and you should be golden,best of luck to ya.  Z

Thanks but all tgey do here now iz plug into the vehicle and sea if there are any codes, which I can control with a tune (r), right?

 

[SHOdded]

If the tune turns off the code for rear O2 sensors, then the car will not be ready for inspection because its' status will show as NOT READY.  So, what folks are saying, stock downpipes, or PPE catted downpipes with stock tune at inspection time are your best bets.
