The 6.7L Cummins is renowned for its torquier-than-tow-power myth — as well as something else not so positive: a finicky EGR system. For some, an EGR delete is the first performance modification they consider. But before jumping into the fray, there’s one question that makes the rest moot: How much does a 6.7 Cummins EGR delete kit really cost?
In this ultimate guide, we’ll break down all the details about pricing, what’s included in a typical kit, installation costs, and how to get the best value when buying a 6.7 Cummins EGR delete kit online.
What Is the EGR System on a 6.7 Cummins?
The Exhaust Gas Recirculation (EGR) system is in place to reduce nitrogen oxide (NOx) emissions by running some exhaust gases back into the engine’s intake. While it reduces emissions, it introduces carbon deposits, soot, and heat into the engine, most affecting:
Intake manifold
Turbocharger
EGR valve and cooler
Cylinder head and valves
This eventually leads to reduced performance, frequent servicing, and even engine destruction.
Why Consider an EGR Delete
Dodge Ram owners of the 6.7L Cummins remove their EGR system for some key reasons:
Better engine reliability
Increased horsepower and torque
Better fuel economy (1–3 MPG improvement)
Lower exhaust gas temperatures (lower EGTs)
No clogged EGR valves or leaky EGR coolers
If you are operating your truck for off-road, racing, or export operations, deleting the EGR is an effective way to protect your engine from irreversible harm.
How Much Does a 6.7 Cummins EGR Delete Kit Cost?
Let’s breakdown:
Cost of Stock EGR Delete Kit
An good-quality 6.7 Cummins EGR delete kit typically costs anywhere from $150 to $350, depending on the quality and brand of materials used.
Lower-end kits might include:
EGR block-off plates
Gaskets
Hose fittings
Higher-end kits might include:
Full EGR cooler replacement hardware
Stainless steel construction
CNC-machined flanges
Coolant reroute components
Enhanced warranty coverage
SPE Tuner offers a full lineup of high-quality, truck-only kits that cost within this bracket. Their offering of Cummins EGR delete kits contains solid, well-engineered choices for each 6.7 Cummins model.
Do I Need to Have the ECU Tuned After the EGR Delete?
Yes. Removing the EGR system requires reprogramming the truck’s ECU to turn off EGR-related codes and eliminate limp mode.
Cost of ECU Tuning
Tuning for a deleted EGR system will cost anywhere from $300 to $600, depending on:
Whether or not you already own a tuner (like EZ Lynk, H&S Mini Maxx, or EFI Live)
If you are buying a package with the delete kit and tuning
The amount of tuning (basic or performance-tuning)
There are a few vendors who offer package deals that have the hardware and preloaded tuner on it at a reduced price.
Optional Add-Ons That Influence Price
When considering total cost, think about whether you’ll also be deleting other emissions systems at the same time. Common additions include:
| Component | Additional Cost Range |
| DPF Delete Pipe | $250 – $500 |
| DEF System Delete (DEF Tank Bypass) | $100 – $250 |
| Downpipe Upgrade | $150 – $400 |
| High-Performance Tuner | $500 – $1,000+ |
Removing the EGR by itself will provide noticeable gains, but most drivers have a complete delete kit (EGR + DPF + DEF) installed for optimal performance and reliability benefits.
DIY vs. Professional Installation Cost
Installation of an EGR delete kit is a medium-level DIY job if you have some basic mechanic knowledge and tools. Budget 4–6 hours for a complete installation.
DIY Installation:
Cost: $0 (if you do it yourself)
YouTube tutorials and furnished instructions assist the majority of people with that.
Professional Installation:
Cost: $400 – $800 (labor charge only)
Recommended in case you’re not handy with coolant line handling or ECU calibration.
Signs You Need an EGR Delete
If your 6.7L Cummins is suffering from any of the following, it might be time to have an EGR delete:
• Check engine light with EGR codes
• Lack of throttle response
• Sagging fuel economy
• Excessive heat or squealing fan noise
• Coolant disappearing without an apparent leak
• Black smoke emanating from the exhaust
These are the majority of these symptoms caused by a defective EGR cooler or valve — both of which are eliminated with a top-of-the-line delete kit.
Choosing the Right Kind of Kit for Your Truck
This is what you should look at when buying a 6.7 Cummins EGR delete kit:
✅ Model-Year Special Fitment: Double verify that the kit fits your Cummins model year (2007.5–2023).
Both ✅ Quality Materials and ✅ Precise Welds are necessities.
Both ✅ Reliable Brand and ✅ Established Vendor are necessities.
Both ✅ Clear Instructions and ✅ Video Guides are necessities.
✅ Tuning Compatibility: Verify the kit is compatible with your preferred tuner.
Legal Considerations
Sole Important Note: Emissions system removal (e.g., EGR) is illegal for on-road use in the U.S. by EPA regulation. Delete kits are only legal when used on:
Off-road or race-use vehicles
Export vehicles
Farm-use trucks not registered for highway use
Always check your local laws before making any modification. The penalties for disobedience can be exorbitant.
Final Thoughts: Is It Worth the Cost?
In regards to engine health, long-term cost savings, and boost in performance, the cost of a 6.7 Cummins EGR delete kit is well worth it for specialty-use or off-road vehicles.
The typical breakdown looks something like this:
| Item | Average Cost |
| EGR Delete Kit | $150 – $350 |
| ECU Tuning | $300 – $600 |
| Installation (optional) | $400 – $800 |
| Total (DIY) | ~$450 – $950 |
| Total (Pro Install) | ~$850 – $1,750 |
By investing in a quality kit like the SPETuner kit, you have your truck running cooler, cleaner, and stronger — without the EGR system drag.
