Well so far in my quest for pure diesel power i have installed the 5" FloPro downpipe back DPF delete exhaust and the H&S mini maxx. Sounds and feels awesome! Its like a whole new truck! Since it is so cold where i live and i don't have a garage I was able to find a guy with a muffler shop. He tore off the old exhaust and put the new one on for me for $90.
Very soon I am planning on buying an AFE stage 2 air intake and Sinister EGR Delete kit. And then the sky is the limit... I have included a video of what the truck sounds like now when started up
