Product Overview
Key Features
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.
