FITMENT
- 2011-2015.5 6.6L Silverado & Sierra Duramax 2500HD/3500HD LML engine with a V-Band Clamp.
- Does NOT Fit 2015.5-2016 models equipped with the 3-bolt flange. Please check underneath your truck!
- Please physically inspect underneath your truck to verify your turbo discharge style before purchasing!
DESCRIPTION
Product Overview
- The factory emissions system on 6.6L Duramax LML engines can create multiple airflow and contamination concerns. The DPF system adds exhaust restriction and heat management demands, while the EGR system recirculates soot into the intake tract.
- The Duramax LML All-in-One Package designed to improve exhaust flow, reduce factory restrictions, and support better throttle response and reliability for modified LML applications.
Key Features
- High-Flow 5" Exhaust System: Replaces restrictive factory DPF exhaust components with mandrel-bent 5" piping and OEM-style hangers for improved airflow and easy installation.
- EGR Delete with High-Flow Intake: Removes the factory EGR cooler and upgrades restrictive intake components to support cleaner airflow into the engine.
- CCV Reroute System: Redirects crankcase vapors away from the intake tract, helping reduce oil contamination in turbo and intercooler components.
- Improved Performance & Efficiency: Reduces factory airflow restrictions, improves throttle response, and supports better towing performance for modified LMM Duramax applications.
- Pre-Loaded Mini Maxx V2 Tuner: Includes pre-configured tuning support for modified configurations, helping manage related diagnostics and optimize engine parameters after hardware upgrades.
FAQ
Q: Why do I need these plugs after removing factory emissions components?
A: After removing components such as the DPF, DEF, and other emissions hardware, some factory sensor connectors are no longer in use. These plugs help keep the original wiring connectors protected from moisture, corrosion, and contamination.
Q: What does the tuner do on a 2011–2016 Duramax LML?
A: The tuner provides ECU calibration support for modified LML Duramax applications. It adjusts engine parameters to work with upgraded exhaust and emissions components while providing diagnostic and monitoring functions.
Q: Why does the LML need tuning after modifying the emissions system?
A: The factory ECM is calibrated around the original DPF, DEF, and EGR systems. Tuning provides the necessary calibration changes for modified vehicle configurations.
Q: What are the benefits of including an EGR kit with the LML package?
A: The EGR components help simplify the factory emissions system, reduce intake contamination, and support improved airflow efficiency on modified LML Duramax applications.
