A cat-back exhaust replaces the pipes and muffler from the catalytic converter to the tip. It changes how the truck sounds and drops a little weight. This one is the MBRP 4-Inch Resonator-Back, Street Profile, Single Side Exit Exhaust, S5246P | 2011-2016 Ford F-250/F-350/F-450, listed to fit the 2011-2016 Ford F-450 Super Duty with the 6.7L Power Stroke V8 (2011-2014 calibration) or 6.7L Power Stroke V8 (2015 update).

why this one — Cat-backs are a sound and looks upgrade first. Treat any power claim as unproven unless the maker publishes a dyno sheet. MBRP Direct lists it at $439.99, and the fitment above is what the listing itself states, not a guess.
