PPE 3" Stainless Down Pipe 11-15 GM 6.6L Duramax LML
Description
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 LML Duramax? 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 11-15 LML 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.

Product Overview: PPE 3" Stainless Down Pipe 11-16 GM 6.6L Duramax
The stock-down pipe on your 11-16 6.6L LML Duramax is not doing you any favors when it comes to performance and sound. Installing this drop-in unit from PPE will allow exhaust to exit the turbo quicker which nets you more power and lower EGTs. Plus the heat wrapping will keep the heat in the exhaust, not the cab. It’s a win-win-win.

Need help. Easy install though
"Fits great but which side does the gasket go one? Where it connects to the turbo or the rest of the exhaust? Not sure why but my exhaust now sits too high and is vibrating/hitting on the bottom of the truck under passenger seat. This my be my own doing but unsure."
