Quick Ship SKU #: PPE-117000400-main PPE 3" Stainless Down Pipe 01-04 GM 6.6L Duramax LB7

Would you drink a milkshake through one of those little coffee stir-style straws you get at the gas station or church? Of course not! You want a straw that's going to deliver that chocolate goodness in a hurry and without a lot of effort. So why are you still forcing your turbo to use a small flat downpipe in your LB7? It wants to move air and be efficient, but that crushed looking pipe isn't letting it breathe easy. PPE has the solution with their Stainless Downpipe for the 01-04 LB7 Duramax. Crafted from 304 Stainless for longevity and reliability and formed with a clean lined flange to a smooth proper round tube for more efficient airflow. Let your turbo breathe easier, and keep your under-hood temperatures down, as the PPE unit is also wrapped in a titanium woven thread for superior heat protection for your other components.
