The EGR Delete Kit for the 2017–2023 L5P Duramax permanently removes the Exhaust Gas Recirculation (EGR) system from your Silverado or Sierra — ending the soot buildup, stuck valves, and hot exhaust gases that keep getting re-routed back into your engine. It's the best-selling Duramax EGR delete kit and a DIY-friendly install.

Every cycle, the EGR pushes hot, dirty exhaust into a clean intake manifold, laying down soot on the valves and manifold walls. EGTs climb under towing load and valve wear accelerates. Deleting the EGR stops that cycle cold and lets the engine run clean.

The kit physically blocks off the EGR circuit and includes all the hardware and gaskets, so there's nothing to source separately. You'll also need a compatible delete tune to update your ECM — the hardware alone won't keep check engine codes away, since the computer still expects the EGR to be working. Removing the system also takes out a major failure point, which is why owners point to a real reliability gain, and many report a 1–3 MPG improvement once the engine is burning cleaner. One avoided EGR cooler or valve repair covers the cost of the kit.

This is compatible with all 2017–2023 Chevrolet Silverado and GMC Sierra Duramax pickup models. Orders process within 1 business day with 4–8 business day standard shipping, and the kit carries a 30-day return policy while unused — once installed, returns aren't accepted.

For off-road/competition use only.

Frequently Asked Questions

An EGR delete kit removes the Exhaust Gas Recirculation (EGR) system, preventing hot exhaust gases from being re-circulated into your engine.
Deleting the EGR system helps prevent carbon buildup, lowers engine temperatures, improves fuel economy, increases reliability, and restores lost power.
No, in fact, many owners report improved engine longevity after deleting. The EGR system often leads to excessive soot buildup, stuck valves, and coolant leaks, especially in heavy-duty diesel engines.
Yes. Simply removing the EGR hardware without turning off its functions in the ECM will trigger check engine lights and cause performance issues. A delete tuner disables the EGR function electronically.
Yes. With the EGR disabled, your engine burns cleaner and more efficiently. Most customers see 1–3 MPG improvements, especially during towing or highway driving.
No. EGR deletes are not emissions-compliant and your truck will not pass inspection in states or provinces that require emissions testing.
Yes. Any emissions modification, including an EGR delete, can void your powertrain warranty. Many owners wait until after their warranty expires
Most kits include block-off plates, replacement coolant lines, high-flow intake tubes, hardware, and installation instructions.
Installation usually takes 3–5 hours depending on your truck model and mechanical skill. Many of our customers do it themselves with basic tools and our guide.
A failing EGR system can lead to overheating, head gasket damage, poor fuel economy, limp mode, and expensive repairs, often over $2,000 if left unresolved.

Egr delete

Good product. For 2020 and up trucks I would recommend providing another coolant plug as well as longer hoses for the coolant reroute.

Parts arrived quickly and were straightforward to install. Fitment was good with only minimal adjustments needed. After 500 miles of driving, the kit is performing flawlessly with no issues to report

Almost perfect-2018 L5P

Great kit; just had two hiccups.
1- The clip on heater core pipe needs to be removed to use the connector that comes in the kit. It works with the factory connector but not the one in the kit.I figured it out but it's not in it directions.
2-There's a small coolant line near the turbo that ends up getting plugged/capped. I had to go to the hardware store and get my own parts for that line. Maybe the right parts were in the kit for a 2020+ but not my 2018...?

Is software included?

thedieseldudes

the full kit would be this product here : https://thedieseldudes.com/products/gm-chevy-duramax-6-6-l5p-full-delete-bundle-2017-2022

this includes the EGR,delete pipe and tuner ( which includes software and everything you need to get it loaded on )

P
Patrick Ritchie

Can this be installed without doing a full delete bundle?

thedieseldudes

Hey man, unfortunately you need to do a full delete to remove the EGR from your truck. These systems are deeply integrated in your truck and so just removing things without doing the proper steps will just hurt your truck
