Pacific Performance Engineering 116120710 OEM Length High-Flow Up-Pipes LMM Duramax with EGR

The Pacific Performance Engineering 116120710 OEM Length High-Flow Up-Pipes are a direct bolt-on replacement designed for 2007.5–2010 GM 6.6L Duramax LMM engines equipped with EGR. Diesel engines generate extreme exhaust temperatures and pressures that cause factory up-pipes to crack or fail over time. PPE engineered these up-pipes to deliver both improved durability and significantly better exhaust flow compared to the stock components.

Key Features:

• Delivers 53% greater exhaust flow compared to OEM up-pipes
• Constructed from 11-gauge 304 stainless steel with 2-inch O.D. tubing and .120-inch wall thickness
• Features internally-sleeved 304 stainless steel bellows engineered to withstand high heat and pressure cycling
• Direct bolt-on replacement — uses factory exhaust manifolds and hardware
• Reduces exhaust back-pressure for faster turbo spool and lower EGTs
• Kit includes both driver and passenger side up-pipes plus PPE 304 stainless steel up-pipe gaskets
• 50-State Emissions Legal — CARB Executive Order No. D-701-20

PPE's high-flow up-pipes are a proven upgrade for any 2007.5–2010 LMM Duramax owner looking to restore or improve exhaust efficiency. The stainless steel construction and superior bellow design ensure long-term reliability under the demanding conditions of diesel operation. Note: A refundable $150.00 core charge applies; core reimbursement is issued upon return of original components to PPE.
