A DPF-back exhaust is the diesel equivalent of a cat-back: it replaces everything from the factory diesel particulate filter rearward (muffler, tailpipe, tips) while leaving the DPF and catalyst completely in place, so it stays emissions-legal.
why this one — MBRP is one of the most established diesel exhaust brands and this ARMOR Lite / Tour Profile kit is purpose-built for the pre-2013 (pre-DEF) 6.7L Cummins body style, in aluminized steel at a lower price point than stainless options.
No manufacturer-published hp/tq figure for this DPF-back exhaust; MBRP markets it on sound/looks/durability, not a dyno number. Diesel DPF-back systems generally do not carry quantified power claims the way gas cat-backs do.
