Hey guys. Just bought a 08 2500 auto 4wd. The previous owner had a full aftermarket exhaust with the dpf and EGR deleted. But the dealership has to re-install all the stock exhaust and EGR. So most likely they are going to flash the system. He had the power play mp 8 installed also. But I'm confused how he had the dpf and EGR deleted with no other tuner. Does the mp 8 delete the codes? I want to put the aftermarket exhaust back on but not sure how to go about it. And I got everything back that the dealership took off.

Any help is appreciated!

 

I would say find the proper tuner to fool the ecm when you put the delete kit back on. But as for the mp8 I don't know?
