  • 2.8L Duramax (LWN): Performance kits for the 2016–2022 Chevy Colorado and GMC Canyon.
  • High-Flow Upgrades: Select kits for LBZ and LMM models include upgraded intake bridges and exhaust up-pipes to further reduce backpressure.
  • Tuning Accessories: We carry SOTF (Switch on the Fly) switches for 2001–2023 models to support multi-map tuning setups.

Why Delete Your EGR System?

  • Eliminate Soot Intake: Stop abrasive carbon from recirculating into your intake manifold, which can cause valve sticking and power loss.
  • Prevent Coolant Leaks: Bypass the factory EGR cooler to avoid internal cracks that lead to overheating and engine damage.
  • Lower EGTs: By removing exhaust gas recirculation, you lower overall Exhaust Gas Temperatures, especially under heavy towing conditions.
  • Precision Engineering: Our kits feature CNC-machined plates and durable hardware for a perfect fit every time.

Note: These products are intended for off-road or competition use only. Always verify your local and federal emissions regulations prior to installation.

Frequently Asked Questions

What is included in a GM Duramax EGR delete kit?
Our EGR delete kits for Duramax engines include CNC-machined EGR block-off plates, coolant reroute or bypass pipes, high-temperature gaskets, clamps, and installation hardware. Everything needed to disable the EGR system safely and cleanly is included in one package.
Which Chevy and GMC Duramax models are supported?
We support all major GM Duramax platforms: LB7 (2001–2004), LLY (2004.5–2005), LBZ (2006–2007), LMM (2007.5–2010), LML (2011–2016), and L5P (2017–2023). Our kits fit Chevy Silverado and GMC Sierra HD models equipped with the 6.6L Duramax diesel engine.
What are the benefits of removing the EGR system?
Removing the EGR system reduces soot buildup inside the intake manifold, improves throttle response, and helps lower exhaust gas temperatures (EGTs). This results in more efficient combustion and reduced maintenance, especially under towing or high-load conditions.
Do I need tuning when installing an EGR kit on my Duramax?
Yes. While some older models may run without tuning, we strongly recommend using a custom tuner to disable EGR-related codes and optimize engine performance. Popular tuning platforms include EFI Live, EZ Lynk Auto Agent 3, and HP Tuners.
Is this kit compatible with the 2020–2023 L5P Duramax?
Yes. We offer EGR and cooler bypass kits specifically for the L5P Duramax engine, including 2020, 2021, 2022, and 2023 Chevy Silverado HD and GMC Sierra HD trucks. These kits are designed for exact fitment and high reliability under load.
Is it legal to install an EGR delete kit on a street-driven truck?
No. EGR delete kits are intended for off-road, race, or agricultural use only. Installing emissions-altering parts on a truck used on public roads may violate local or federal emissions laws. Always verify compliance before modifying your vehicle.
Why choose TunerDepot for your Duramax EGR upgrade?
TunerDepot offers premium-quality EGR kits tested for real-world durability and performance. With direct-fit solutions for every generation of Chevy and GMC Duramax diesels, we make it easy to eliminate failure-prone emissions parts and unlock your truck’s full potential.
