PPE OEM-Length Replacement High-Flow Up-Pipe Kit (2017-2026 GM 6.6L Duramax) - (116122000
Overview
PPE's OEM-Length Replacement High-Flow Up-Pipe Kit is engineered to upgrade the restrictive factory up-pipes found on 2017-2026 GM 6.6L Duramax engines. Designed to improve exhaust flow and support better turbocharger performance, this kit offers a durable, direct-fit solution for worn or corroded OEM components.
Enhanced Exhaust Flow
The stock up-pipes feature tight bends and a narrow bottleneck that limit airflow and contribute to higher pumping losses. PPE eliminates these restrictions with a high-flow design that increases exhaust flow by up to 46%, helping the turbo operate more efficiently and improving overall engine response.
Premium Stainless Steel Construction
Built from high-quality stainless steel, each up-pipe features a three-layer internally sleeved bellow designed to withstand extreme heat and pressure cycles. This robust construction ensures long-term durability and smoother, more consistent exhaust movement.
Direct Bolt-On Replacement
These up-pipes bolt directly to the OEM exhaust manifolds with no modifications required. PPE also includes stainless steel gaskets to ensure a clean, leak-free installation.
