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 4" 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
- Optimized Fast Turbo Spool: 4" pipe diameter maintains ideal exhaust gas velocity for faster turbocharger spool-up, crisp throttle response, and minimal cab drone.
- Reduces EGTs & Ends Active Regens: Replaces the heavy, restrictive DPF canister with a smooth 4" race 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: What is the main difference between this kit and the non-muffler kit?
A: Adds a muffler to eliminate cab drone and a CCV Reroute to keep oil out of your turbo and intercooler—making it the most complete, comfortable, and protective package for 15.5-16 LML trucks.
Q: What is the advantage of the muffler version?
A: The integrated high-flow muffler reduces harsh exhaust tones and highway drone while maintaining improved airflow. It is an ideal choice for daily driving, towing, and work trucks that need better exhaust flow with a more comfortable cabin sound level.
Q: Will this make my truck louder?
A: Yes, you will notice a deeper diesel exhaust tone compared with the factory emissions system. The muffler version provides enhanced turbo sound, a deeper exhaust note, and reduced highway drone compared with a straight pipe setup.
Q: Can I install this with my factory exhaust?
A: Yes. This pipe is designed as a direct replacement section that connects with the factory exhaust system after removing the factory emissions components. No complete exhaust replacement is required.
