TruckTok 2011-2016 6.6L Chevy Duramax LML Up-Pipe & EGR Cooler Delete Kit (Passenger Side)

FITMENT

• 2011-2016 6.6L Chevy GMC Duramax LML 2500 HD 3500 HD Diesel.

DESCRIPTION

Product Overview

• The 6.6L Duramax LML is known for its power and reliability, but factory exhaust and EGR components can create airflow restrictions and contribute to carbon buildup over time. The OEM up-pipe design limits exhaust flow before the turbocharger, while the EGR system can introduce soot into the intake system.
  
• The LML High-Flow Up Pipe & EGR Delete Kit combines a durable high-flow up-pipe with a precision-engineered EGR delete assembly to improve exhaust flow, simplify the factory system, and support a cleaner intake environment. this kit delivers improved airflow efficiency and enhanced diesel performance potential.

Key Features

• Enhanced Exhaust Velocity to Turbo: Replaces the pinched factory up-pipe with smooth, high-flow stainless steel tubing to accelerate exhaust gas velocity going into the turbocharger for noticeably faster boost recovery.
  
• Reduces Backpressure: Unblocks exhaust manifold restriction right off the exhaust valves, significantly lowering EGTs during heavy towing and high-boost applications.
• Stops Intake Carbon Sludge & Coolant Leaks: Completely removes the factory EGR cooler, preventing abrasive soot from clogging intake valves and eliminating internal coolant loss risks.
• Saves Installation Labor: Installing the up-pipe and EGR delete kit simultaneously avoids duplicate teardown shop labor costs around the tight rear engine compartment.

FAQ

Q: What is the benefit of replacing the factory Up-Pipe on a Duramax LML?

A: The factory up-pipe design can create exhaust flow restrictions before the turbocharger. Replacing it with a high-flow up-pipe helps improve exhaust flow efficiency, reduce restriction, and support quicker turbo response under load.

Q: Why install the Up-Pipe and EGR Delete together?

A: Both components are located in a difficult-to-access area behind the engine near the firewall. Installing them together improves efficiency by reducing repeated teardown and labor time during installation.

Q: Does this kit help address EGR cooler-related concerns?

A: The kit removes the factory EGR cooler from the system and includes components designed to properly reroute coolant flow. This simplifies the factory EGR system and helps maintain a cleaner intake environment.

Q: What happens if I drive the truck after installation without custom tuning?

A: The factory ECM may detect missing emissions system components and trigger diagnostic codes or reduced-power modes. Proper tuning may be required after installation to match your vehicle configuration and ensure optimal operation.
