Okay my mbrp exhaust gets rid of my cat. Which in the state of NC you need to have emissions test done. So my question to you guys without buying a tuner saving money up now for one. How can i get it so my car reads the rear 02 sensor is working properly.

You can assemble one for just a few bucks until you can save the cash for a tuner...

How does your setup deletes the cat? Did you install a race header? IMO, installing a flex-back MBRP exhaust will not delete the cat. But, since yours is an 07, I am not 100% sure. You can add a sparkplug fouler to the O2 sensor to trick the sensor.
