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 benefit of a Full Exhaust System with a Muffler over a straight pipe or race pipe?
A: Straight-pipe exhaust can create noticeable cabin drone during highway driving. The high-flow muffler helps reduce harsh exhaust frequencies and noise while maintaining strong airflow and a deeper diesel tone.
Q: Will this kit fit my 2015–2016 Duramax LML truck?
A: LML trucks use different exhaust connection styles depending on the production date. Verify your factory exhaust connection (V-clamp or 3-bolt flange) before ordering to ensure proper fitment.
Q: What is the difference between a DPF race pipe and a full exhaust system?
A: DPF race pipe replaces only the factory DPF section, while a full exhaust system replaces the complete exhaust path for increased airflow, a deeper exhaust tone, and a cleaner upgraded appearance.
Q: Can the included tuner read codes and monitor engine data?
A: Yes. The tuner can read and clear compatible OBDII trouble codes and function as a digital gauge monitor, displaying available parameters such as EGT, boost pressure, coolant temperature, transmission temperature, and other engine data.
