PPE Exhaust Manifold to Up-Pipe Gasket 17-26 GM 6.6L Duramax
If you’ve ever chased down that annoying ticking sound or faint exhaust smell, there’s a good chance a small gasket like this is the culprit. This exhaust manifold to up-pipe gasket seals the lower connection on your 6.6L Duramax, keeping everything tight so your truck runs the way it should. When that seal is solid, you’ll notice smoother performance, more consistent turbo response, and no unwanted noise under load.
It’s built from a multi-layer stainless steel design, so it can handle the heat and pressure without wearing out quickly. Whether you’re reinstalling factory parts or running PPE manifolds, it fits right in and does its job without hassle. It’s a simple replacement, but one that makes a real difference in drivability, reliability, and long-term durability.
