Pacific Performance Engineering 116120607 OEM Length High-Flow Up-Pipes 06-07 GM 6.6L Duramax LLY/LBZ with EGR

The Pacific Performance Engineering (PPE) 116120607 OEM Length High-Flow Up-Pipes are a direct bolt-on upgrade over factory up-pipes for 2006–2007 GM 6.6L Duramax LLY/LBZ diesel engines equipped with EGR. Designed to replace the weak OEM bellows that commonly fail due to constant heat cycling and exhaust pressure, these PPE up-pipes deliver significantly improved durability and flow performance without requiring any modifications to your factory exhaust manifolds.

Key Features:

• Constructed from 11-gauge 304 stainless steel with a 2-inch O.D. and 0.120-inch wall thickness for superior strength and corrosion resistance
• Features PPE's 304 stainless steel, internally-sleeved bellows engineered to withstand extreme temperature and pressure fluctuations
• 53% greater exhaust flow compared to stock up-pipes for improved turbo spool and engine performance
• Direct bolt-on fitment to OEM factory exhaust manifolds — no cutting, welding, or modifications required
• Designed specifically for use with EGR-equipped engines and OEM-style exhaust manifolds
• Replaces failure-prone factory bellows that degrade under high-heat diesel operating conditions
