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 4" Exhaust System: Replaces restrictive factory DPF exhaust components with mandrel-bent 4" 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: What sensors are monitored by the LML emissions system?
A: The factory LML emissions system uses multiple sensors, including DPF pressure sensors, EGT sensors, NOx sensors, DEF level/quality sensors, and other ECM inputs to manage emissions operation.
Q: Does this kit address DEF system warning messages?
A: The included tuner provides calibration support for DEF/SCR-related systems on compatible LML Duramax applications.
Q: Why is a tuner required when upgrading the LML exhaust and emissions components?
A: The factory ECM is calibrated for the original emissions system. A compatible tuner provides ECU calibration support for modified exhaust and emissions configurations.
Q: Can the tuner monitor engine data?
A: Yes. The tuner can function as a digital gauge monitor and display available engine parameters such as EGT, boost pressure, coolant temperature, transmission temperature, fuel pressure, and other vehicle data.
