Upgrading to aftermarket manifolds and up-pipes on your 2020-2024 GM 6.6L Duramax L5P is a great way to unlock additional power and performance. These high-quality up-pipes replace the restrictive factory components, providing improved exhaust flow and reduced backpressure. The result is lower Exhaust Gas Temperatures (EGTs) and a significant boost in both horsepower and torque for your GM 2500HD/3500HD. GM Duramax Fitments: 2020, 2021, 2022, 2023, 2024 GM 6.6L Duramax. Submodel Fitments: WT, Custom, LT, LTZ, High Country, 1LT, 2LT, Pro, SLE, SLT, AT4, Denali. Some exceptions apply, please see individual product pages for specific fitments.
