2017-2020 L5P DURAMAX HIGH FLOW UP PIPES

Upgrade your exhaust flow and unlock the true potential of your 2017–2020 L5P Duramax with these High Flow Up Pipes. Designed to eliminate the factory restrictions, these up pipes improve exhaust gas flow from the manifolds to the turbo, helping your truck breathe easier and perform harder.

Constructed from high-quality stainless steel, these up pipes are built to handle extreme heat and pressure while resisting cracking and warping—common issues with OEM components. The increased diameter and smoother bends reduce backpressure, allowing for quicker turbo spool, improved throttle response, and increased overall efficiency.

Perfect for performance builds or replacing failure-prone factory pipes, these high flow up pipes are a must-have upgrade for anyone looking to enhance reliability and power.
