Actually my buddy who coworks for xdp doing installs and was ford diesel tech says there really after the dpf part. In instance the egr delete on a 6.0 diesel is a good thing cause it helps prolong the motor. I usually get complements for my car from people like oh that things sounds nice n looks nice. Some old guy thought i had a 454 under the hood lol.
