PPE REPLACEMENT HIGH FLOW UP-PIPES 116120710 | 2007.5-2010 6.6L Duramax LMM

Replace the cracked or leaking factory up-pipes on your 2007.5–2010 GM 6.6L Duramax with the PPE 116120710 Replacement High-Flow Up-Pipes. Engineered as a direct bolt-in upgrade, these high-performance up-pipes deliver up to 53% greater flow than the factory components, helping reduce exhaust restriction and improve overall engine efficiency.

Constructed from heavy-duty 11-gauge T304 stainless steel, these up-pipes are built to withstand the extreme heat and pressure generated by diesel engines. The internally sleeved stainless steel bellows provide exceptional durability while accommodating thermal expansion and engine movement. The increased flow capacity helps lower exhaust gas temperatures, reduce backpressure, and promote quicker turbocharger spool-up.

Designed for hassle-free installation, these up-pipes are installed at the factory location and include the necessary gaskets for service or replacement work.
