FITMENT
- 2020–2022 3.0L Chevrolet Silverado 1500 LM2 Diesel.
- 2020–2022 3.0L GMC Sierra 1500 LM2 Diesel.
DESCRIPTION
Product Overview
- The 3.0L Duramax LM2 is known for its excellent efficiency and towing capability, but the factory emissions system adds complexity and restriction to the exhaust and intake systems. Over time, components like the DPF, catalytic converter, and EGR system can contribute to exhaust restriction, soot buildup, and increased maintenance concerns.
- The LM2 Turbo-Back & EGR Delete Kit provides a upgrade solution by combining a high-flow 3" mandrel-bent exhaust pipe with EGR delete components. this kit helps improve exhaust flow efficiency, simplify the factory system, and support a cleaner operating environment for off-road and competition applications where permitted.
Key Features
- High-Flow Exhaust Upgrade: Replaces the factory DPF assembly with a smooth-flowing 3" exhaust pipe design to help reduce exhaust restriction and improve overall exhaust flow efficiency.
- Improved Exhaust Flow & Reduced Regeneration Demand: By reducing exhaust restriction after the turbocharger, helps improve exhaust gas flow characteristics and reduce the additional heat and fuel demands associated with frequent regeneration cycles.
- Cleaner Intake System Design: The EGR cooler delete help simplify the factory EGR system and reduce the potential for soot buildup inside intake components, supporting a cleaner intake environment.
- Improved Turbo Response & Throttle Feel: With reduced exhaust restriction, the 3.0L LM2 turbocharger can operate more efficiently, helping improve throttle response and overall driving performance.
FAQ
Q: Why is a 3" pipe diameter used for the 3.0L Duramax LM2 turbo-back exhaust?
A: 3" mandrel-bent system is optimized for the airflow capacity and displacement of the 3.0L Inline-6 engine. It provides maximum exhaust gas velocity and EGT reduction without sacrificing low-end throttle response or causing excess cab drone.
Q: What are the benefits of deleting the EGR cooler on a 3.0L LM2 diesel?
A: Removing the factory EGR cooler permanently stops hot, abrasive exhaust soot from entering the intake manifold. This prevents sticky carbon sludge from choking intake valves, lowers intake air temperatures, and eliminates catastrophic internal coolant leak risks.
Q: Will this kit reduce EGT (Exhaust Gas Temperature)?
A: Reducing exhaust restriction can help improve exhaust flow characteristics and may help manage exhaust temperatures under certain operating conditions.Actual EGT changes depend on driving conditions, tuning, load, and other vehicle modifications.
Q: Is custom ECM tuning required after installing this kit?
A: Yes, mandatory. Removing the DPF filter and EGR cooler alters engine control sensor signals. Custom ECM off-road delete tuning is required to disable DTCs, clear the CEL, and keep the truck out of limp/derate mode.
