Delete Kit FAQs for Powerstroke, Cummins & Duramax

A delete kit removes factory emissions components (like EGR, DPF, or DEF systems) from diesel engines. This boosts performance, fuel efficiency, and engine longevity. Popular options include EGR delete kits, DPF delete kits, and diesel delete kits, tailored for engines like the 6.7 Cummins, Duramax, or 6.7 Powerstroke.

An EGR delete kit for Duramax engines (e.g., L5P delete kit or LML delete kit) removes the Exhaust Gas Recirculation system. This stops hot exhaust gases from cycling back into the engine, reducing carbon buildup, improving throttle response, and preventing overheating.

The best DPF delete kit for Duramax engines (like the 3.0 Duramax delete kit or LBZ EGR delete kit) depends on your model year. Our stainless steel kits include everything for a clean installation and are compatible with factory sensors.

The 6.7 Cummins delete kit (with 6.7 Cummins EGR delete components) is our top seller. It eliminates the DPF and EGR systems, paired with a high-flow exhaust for maximum horsepower and torque gains.

Disconnect the battery. Remove the factory EGR valve and cooler. Install the EGR delete kit block-off plates and reroute coolant lines. Reconnect the battery and tune the ECU (recommended for optimal performance).

Remove the DPF and catalytic converter. Install the DPF delete kit’s straight pipe or catalytic converter delete kit. Secure clamps and reconfigure sensors. Tune the engine to avoid error codes.

The 6.7 Powerstroke delete kit includes heavy-duty block-off plates and coolant bypass hoses. It’s designed to handle extreme temps and works with factory turbo setups.

Drain the coolant. Remove the EGR cooler and valve. Install the 6.0 Powerstroke EGR delete kit components (plates, gaskets, hoses). Refill coolant and tune the ECU.

Our 6.7 Powerstroke delete kit bundles a DPF/EGR delete with a 4-inch exhaust. It’s ideal for towing and daily driving, with no welding required.

DPF delete kits remove the Diesel Particulate Filter to improve exhaust flow. EGR delete kits eliminate the Exhaust Gas Recirculation system to reduce engine heat and carbon buildup. For full emissions removal, pair both with a DEF delete kit.
