FITMENT
- 2015.5-2016 6.6L Silverado & Sierra Duramax 2500HD/3500HD LML engine models with the 3-bolt flange.
- Does NOT Fit 2011-2015.5 model with the V-Band Clamp style.
- 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 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 is the difference between this Full Exhaust Kit and a 4" DPF Race Pipe Kit?
A: 4" DPF Race Pipe replaces only the factory DPF/SCR section while keeping the stock rear exhaust components. A 4" Full Exhaust Kit replaces the complete exhaust system from the downpipe connection to the rear tailpipe, providing increased airflow, reduced restriction, and a deeper exhaust tone.
Q: Will this full 4" exhaust fit properly without hitting the spare tire or rear axle?
A: The system is designed with OEM-style routing using precision mandrel-bent pipes and factory-style hangers for proper clearance around the frame, axle, and spare tire areas.
Q: Why is the EGR delete included with the full exhaust system?
A: The exhaust upgrade improves exhaust flow, while the EGR delete helps reduce soot recirculation and intake contamination for a more complete airflow upgrade.
Q: Can the tuner read and clear trouble codes?
A: The tuner provides ECU calibration support for the modified exhaust and emissions configuration while offering diagnostic functions and available engine monitoring features. and read and clear compatible OBDII trouble codes and function as a digital gauge monitor for available engine parameters.
