The 3.5" Turbocharger Downpipe for the 2017–2023 L5P Duramax removes the DOC (Diesel Oxidation Catalyst) and increases exhaust flow straight out of the turbo, improving performance. Also called the turbo direct pipe, it fits the Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD with the 6.6L Duramax L5P — pickup trucks only.
