Headers replace the cast exhaust manifolds with tuned tubes so each cylinder has a smoother path out. This one is the Pacific Performance Engineering Manifolds and Up-Pipes GM 2017-2021+ L5P PPE Diesel, listed to fit the 2017-2021 Chevrolet Silverado 2500HD/3500HD with the 6.6L Duramax V8 (L5P).

why this one — This is a long, hot, awkward job on a truck. Budget for a shop and for a tune afterward. T3 Speed Shop lists it at $1349.99, and the fitment above is what the listing itself states, not a guess.
