My BIL tried to license his deleted 08 RAM in Arizona and they rejected it after the mirror look under it and the EGR stuff missing under the hood with caps installed. And he failed to keep the deleted items given to him when he bought it. RAM/Cummins is coming out with a new system that is going to be completely down stream of the engine. No EGR. Any repair shop that is deleting truck is putting themselves up for large fines in the fed suits walk in.
Our son's major West Coast wholesale exhaust system supplier with not even stock delete pipes anymore.
