DESCRIPTION
Product Overview
-
Stock 6.6L Duramax LML setups suffer from choking exhaust restriction and long-term intake contamination. High exhaust backpressure causes power-robbing heat build-up under heavy towing, while recirculated EGR exhaust gases continuously contaminate your engine’s fresh air supply with sticky carbon deposits.
- Reclaim true engine breathing with this all-in-one LML 4" Race Pipe & EGR Delete Package. Designed to maximize exhaust velocity and isolate carbon soot from your intake system, this upgrade lowers towing temperatures, restores instant throttle response, and cleans up your underhood configuration.
Key Features
- Fits late-build trucks cleanly with precision 3-bolt flange geometry matched to the factory downpipe connection.
- Replaces the DPF and CAT with a 4" pipe carrying a built-in high-flow muffler that tames harsh tones and highway drone.
- Deletes the EGR cooler and reroutes the CCV oil mist so soot and oil stay out of the turbo and intercooler, keeping them clean.
- Combines pipe, EGR, and CCV installs into one workflow to minimize labor costs in the cramped engine bay.
FAQ
Q: How does this kit differ from the non-muffler version?
A: It adds a muffler to cut cab drone and a CCV reroute to keep oil out of the turbo and intercooler — the most complete, comfortable, and protective package for 15.5-16 LML trucks.
Q: What’s the advantage of the muffler version?
A: The integrated high-flow muffler softens harsh exhaust tones and highway drone while preserving airflow, ideal for daily driving, towing, and work trucks.
Q: Will this make the truck louder than the stock system?
A: Yes, you’ll notice a deeper diesel tone than the factory system. The muffler version adds turbo sound and a richer note with less highway drone than a straight pipe.
Q: Will this work with my existing factory exhaust?
A: Yes. This pipe is a direct-fit replacement section that bolts up to your factory exhaust once the emissions components are gone, so there’s no need to replace the entire system.
