Bring out the full potential of your GMC Sierra or Chevrolet Silverado LM2 3.0L Duramax with a complete delete solution from Diesel Lion. Built for drivers who want stronger performance, sharper throttle response, and a cleaner, more efficient setup, this package is designed to deliver the results your truck should have had from the factory.
Delete tuning helps unlock increased horsepower and torque, improved acceleration, and more responsive performance throughout the RPM range. The result is a truck that feels stronger, pulls harder, and responds more consistently under load.
This tuning also refines fuel delivery and engine calibration for improved overall efficiency and drivability. With optimized tuning and reduced exhaust restriction, your LM2 can run cleaner and more efficiently while maintaining the performance gains you expect.
By removing restrictive emissions components and recalibrating engine parameters, this setup improves exhaust flow and reduces backpressure. That can help support engine longevity and reduce the chance of issues caused by plugged or restrictive exhaust components.
If you want a cleaner engine bay, improved performance, and a more aggressive overall setup, this LM2 complete delete kit delivers exactly that.
3.0L Duramax EGR Delete Kit
Kit Includes
- High-quality 4-ply silicone coolant hose (1)
- Caps (2)
- Ground cable (1)
- Blocker plates for the EGR valve and cooler (2)
- Intake plug (1)
This kit allows for the removal of the EGR cooler and valve, exhaust valve, and EGR cooler pipe.
EGR Cooler and Valve Removal:
The LM2 3.0L Duramax EGR Delete Kit is designed to eliminate the restrictive EGR cooler and valve, reducing the limitations caused by recirculated exhaust gases. Removing these components helps improve airflow and reduce carbon buildup for a cleaner and more efficient combustion process.
Exhaust Valve Elimination:
The exhaust valve is a common source of carbon buildup and reduced functionality over time. When combined with the race pipe, the LM2 EGR Delete Kit removes this potential restriction, helping promote smoother operation and improved reliability from critical engine components.
EGR Cooler Pipe Blockage:
The kit also includes a solution for blocking the EGR cooler pipe, preventing the unwanted recirculation of hot exhaust gases.
Professional installation is strongly recommended, as removal of essential engine bay components is required to extract the OEM system.
FLOPRO 3.0L Duramax Cat and DPF Delete Pipe
Professional installation is strongly recommended, as removal of essential engine bay components is required to extract the OEM system.
Fabricated from durable 16-gauge aluminized steel, this exhaust system is built for a precise fit using machined flanges and lap-joint style clamps. It is designed to improve performance, reduce exhaust gas temperatures, and increase airflow, all while giving your truck a deeper, more aggressive sound.
Uses the existing muffler.
