I have had the h&s mini max with just the delete for about a year now. Today I installed the down pipe. It took me two hours by my self. I would suggest getting a buddy to help. Now the 6.7 cummins sounds like it should and it blows smoke with out the tuner turned on. You need to drop your tranny cross member and passenger front fender skirt to install. I am very happy with the down pipe and dpf delete by afe. And the h&s tuner was a good choice my buddies that have smarties wish they got an h&s. Most important xdp has great customer service. I have bought all of my miss from them and I will continue to do so.
