A DPF-back exhaust is the diesel equivalent of a cat-back: it replaces everything from the factory diesel particulate filter rearward while leaving the DPF and catalyst fully in place, so it stays emissions-legal.
why this one — Diamond Eye is a well-known DPF-back specialist and this dual-outlet 409-stainless kit is purpose-fit to the 2013-2018 Crew Cab Short Box 6.7L Cummins - one of the best-documented model/cab/bed combos for this era.
