Overview

The Pacific Performance Engineering 116120405 is a set of replacement high-flow up-pipes designed for 2004.5-2005 GM 6.6L Duramax LLY engines. Constructed from 11-gauge, 304 stainless steel with a .120-inch wall thickness and 2-inch outer diameter, these up-pipes feature internally sleeved bellows. They offer a 53% increase in airflow compared to stock, significantly lowering Exhaust Gas Temperatures (EGTs), reducing back pressure, and promoting quicker turbo spool-up.

Part #: 116120405

Diesel engines (even stock) produce high temperatures and pressures. OEM up-pipes eventually fail from constant temperature and pressure fluctuation.PPE has taken OEM replacement to a new level. PPE OEM Up-Pipes allow 53 percent greater flow than stock. PPE OEM Up-Pipes are a direct bolt-on to your factory manifolds. But unlike factory parts, PPE OEM Up-Pipes are manufactured from 11 gauge 304 stainless steel and include our superior PPE 304 stainless steel, internally-sleeved bellows that can take the abuse of high temperature and high pressure.Features:OEM Length Replacement High Flow Up-Pipes LLYDirect bolt-on replacement to factory exhaust manifoldsSignificant reduction in exhaust back-pressureFree-flowing stainless steel inner liner bellowsStainless steel 11-gauge .120-inch wall, 2-inch O.D.
