- Please physically inspect underneath 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 choose a 5" exhaust system for my 2015.5–2016 Duramax LML?
A: The 5" exhaust system provides greater exhaust volume and airflow capacity compared with the factory system, making it ideal for heavy towing, higher-power builds, and drivers looking for a deeper diesel exhaust sound.
Q: What does the included tuner do?
A: The included tuner provides ECU calibration support for 2015.5–2016 Duramax LML applications. It works with the modified exhaust, EGR, and CCV configuration while providing diagnostic and engine monitoring functions.
Q: Why is the EGR delete included with the 5" exhaust package?
A: The exhaust system improves exhaust flow, while the EGR delete helps reduce exhaust soot recirculation and intake contamination for a more complete airflow upgrade.
Q: Does this kit include everything needed for installation?
A: This all-in-one package includes the tuner, 5" exhaust system, EGR delete components, and CCV reroute hardware. Additional supplies such as coolant or installation tools may be required depending on vehicle condition.
