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 6.6L Duramax LML engines is designed for emissions compliance, but the DPF system can create additional exhaust restriction and increase heat management demands under heavy load. At the same time, the factory EGR system recirculates exhaust gases back into the intake system, which can contribute to soot and carbon buildup over time.
- The LML 5" DPF Delete Pipe & EGR Delete Package combines a race pipe with EGR delete components. helps improve exhaust flow efficiency, reduce system restriction, and simplify the factory emissions configuration for off-road and competition applications where permitted.
Key Features
- Massive Exhaust: Replaces the factory exhaust system from the DP back with smooth 5" pipe—delivering maximum exhaust flow, lowest possible EGTs, and a deep, aggressive diesel tone.
- Reduces EGTs & Ends Active Regens: Replaces the heavy, restrictive DPF canister with a smooth 5" straight pipe to eliminate primary exhaust backpressure and stop fuel-draining regenerations.
- Dual-Source Intake Protection: Removes EGR soot and reroutes CCV oil mist away from the engine—stopping carbon sludge buildup and keepin turbo, intercooler, and intake tract dry and claen.
- Saves Maximum Labor & Shop Costs: Installing all three systems at once avoids duplicate teardown shop labor around the tight rear engine compartment and chassis.
FAQ
Q: How do the 5" exhaust, EGR Delete, and CCV Reroute work together for maximum performance?
A: Upgrade your Duramax with improved exhaust flow, reduced soot buildup, and a cleaner intake system. The 5" straight pipe, EGR delete, and CCV reroute work together to help your truck breathe better and perform more efficiently.
Q: What makes a 5" Downpipe-Back system different from a standard 4" race pipe?
A: The 5" DP-Back system replaces the full exhaust section from the downpipe outlet rearward, providing increased exhaust flow, reduced restriction, and a deeper diesel exhaust sound compared with a 4" race pipe setup.
Q: What does the EGR cooler delete do?
A: The EGR cooler delete removes the factory EGR cooling components and simplifies the exhaust gas recirculation system, helping reduce potential coolant and soot-related issues associated with the factory setup.
Q: What should I do with the factory EGT and NOX exhaust sensors after removing the DPF?
A: After completing the required vehicle setup, the factory EGT and NOx sensors may no longer be used. To protect the exposed wiring connectors from moisture, corrosion, and debris, using a Harness plug kit to keep the factory harness clean and weather-resistant.
