aFe Power Large Bore-HD 4" 409 Stainless DPF-Back Exhaust w/ Black Tip (49-43106-B)

A DPF-back exhaust system replaces the factory muffler and tailpipe section with a larger 4-inch mandrel-bent pipe and a black exhaust tip, deepening the truck's sound without touching the factory diesel particulate filter or catalytic converter.

why this one — This is aFe's heavy-duty stainless option for the 3.0L Power Stroke. It bolts to factory hanger/mounting points and keeps the factory DPF and catalyst in place - a sound and finish upgrade only, not an emissions modification.
