Ensure a Leak-Free Seal with PPE

If you're chasing down an exhaust leak on your L5P Duramax, there’s a good chance your up-pipe gaskets are the culprit. The PPE Stainless Steel Up-Pipe Gasket Set is a smart, long-term fix that not only solves the problem—it’s an upgrade over the stock components in every way. Whether you're doing a repair or installing new up-pipes, these gaskets are designed to hold up under the kind of heat and pressure your Duramax sees on a regular basis. This set is made specifically for 2017–2025 Silverado and Sierra 2500HD/3500HD trucks with the 6.6L L5P. It includes four gaskets total—everything you need for a full replacement. PPE uses multi-layered 301 stainless steel, which is far more durable than the standard material found in factory gaskets. That layered design, combined with a rolled edge, creates a tighter, more consistent seal between the manifold and turbo inlet.

Built to Handle Extreme Stress

Where the factory gaskets tend to break down over time—especially under high heat, towing loads, or performance upgrades—these PPE gaskets are built to take that kind of abuse. They handle the extreme temperature swings of a diesel engine without warping or failing, which helps prevent future leaks and the headaches that come with them. Another big plus is that these gaskets work with both stock and aftermarket up-pipes. So whether you’re staying OEM or installing a high-flow setup, you won’t have to worry about compatibility. And since they’re a direct fit, installation is straightforward—no weird trimming or modifying to make things work.
