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 — aFe is one of the largest diesel performance brands and offers both stainless and aluminized versions of this 5in DPF-back system with a choice of black or polished tips.
AFe markets ATLAS systems on flow/EGT benefits, not a quantified hp/tq figure, for this SKU.
