6.7 Cummins Delete Cost: 2026 Prices & What to Expect

Deleting a 6.7L Cummins isn't as simple as removing one part. When truck owners talk about a "full delete," they're referring to removing or bypassing several emissions components that sit between the engine and the exhaust.

How much does it cost to delete a 6.7 Cummins? The full cost to delete a 6.7 Cummins can be $1,500-$4,500 in 2026.

Kits run $800-$2,000, labor $500-$1,500. Gains include 30-80 HP and 1-3 MPG. But fines reach $10,000.

If you own a 2022 or newer model, the cost to delete and tune a 6.7 Cummins can easily jump into the $3,000–$6,000+ range due to ECU requirements and updated tuning methods.

How much to delete a 6.7 Cummins matters because it helps you set realistic expectations. If someone quotes you a full delete for $300, it's not legitimate. If another shop wants $8,000 for a simple DPF/EGR job on a 2015 truck, that's too high.

You're here to figure out the average cost to delete a 6.7 Cummins, what's fair, and that's exactly what this guide covers.

Average Cost to Delete 6.7 Cummins

Let's start with the averages cost. Average full delete costs $2,000-$3,500 total. Parts $1,000-$2,000, labor $500-$1,500. DIY saves $500-$1,000.

Here we show you the average cost to delete a 6.7 Cummins below to give you a clue which is the best fit with your RAM 2500/RAM 3500 truck and budget.

Average Pricing Overview (Parts + Labor)

Delete Type	What's Included	Price Range	My Spend
Budget DIY Setup	DPF/CAT delete pipe, basic EGR block-off kit, entry-level tuner	$0 but tools $100-$300
Standard Shop Install	Pipe, EGR delete kit, professional tuning, labor	$500 – $1,500+	$900
2022+ Full Delete (Parts Only)	Replacement ECU, tuning hardware, tuning credits, exhaust parts	$1,500-$2,000	$1,900
Heavy-Duty Performance Build	High-end tuner, full exhaust, upgraded intake, custom tuning	$3,000 – $7,500+

The majority of owners belong to the second category.

Typical Overall Cost 

The average cost to delete a 6.7 Cummins with a shop installation is approximately $2,000-$3,500 in total. My 2023 delete: $2,800.

These numbers cover parts and labor combined, which is what most owners want to know.

• The cost to delete a 6.7 Cummins depending on the parts they choose and how they are installed.
• Tuning prices also depend on whether the tuner supports your model year, especially the newer trucks that often need upgraded or unlocked ECUs.

Parts Plus Labor

Pipes $300-$600. EGR kit $150-$350. Tuner $500-$1,000. Labor 6-10 hours at $100/hour.

For shop intall, in tuning, some shops offer tuning and exhaust services together, while others charge individual pricing.

Regional Variations

West Coast: $3,000+. Midwest: $2,200. South: $1,800. Shop rates differ.

If you want to DIY (do it yourself), the price can drop sharply. A typical DIY approach is:

• $150–$350 for a 6.7 Cummins DPF delete pipe
• $150–$300 for an EGR block-off or full replacement kit
• $300–$600 for a tuner (MM3, EFI Live, HP Tuner, or H&S Mini Mixer, depending on the year)

Add those together and your total average 6.7 Cummins delete cost lands in the $450–$950 range. If your RAM truck is older and the hardware is compatible with common tuning platforms, DIY becomes much more practical.

6.7 Cummins Delete Cost Breakdown

This section goes deeper into each part so you understand exactly where your money goes.

DPF pipe $300-$800. EGR kit $150-$400. Tuner $500-$1,200. Options add $200-$1,000.

Every delete kit involves four key categories: the DPF/CAT delete pipe, the EGR delete kit, the tuner, and any optional upgrades.

1. DPF/CAT Delete Pipe Costs

The exhaust system is usually the first step people think of. The delete pipe replaces the DPF, DOC, and sometimes the SCR, depending on your truck's layout. You have a few decisions to make here.

Stainless vs. Aluminized Steel

• Aluminized pipes are cheaper and perfectly fine for most climates.
• Stainless steel pipes are more expensive but are beneficial as they are durable in wet or salty conditions.

Stainless $500-$800. Aluminized $300-$500. The price can vary depending on the brand and the thickness. My stainless no rust at 2 years.

4" vs. 5" Exhaust Options

The 4-inch pipe tends to be the standard choice because it fits more easily with stock components.

A 5-inch pipe offers a deeper tone and slightly lower exhaust temps, but may require more trimming or extra clamps.

4" quiet $400. 5" loud power $600. 5" my choice for tow. The cost difference depends on your preferred exhaust brand.

Price Range for Pipes

A typical DPF/CAT delete pipe for the 6.7L Cummins runs between $300 and $800. The cheaper pipes are aluminized and designed for easy installation. The higher-end ones are stainless with better weld quality.

This is also where some owners consider full exhaust kits. If you go beyond a simple delete pipe to a full turbo-back system, your total can increase by another $200 to $1,000, depending on the brand.

2. EGR Delete Kit Costs

The EGR system introduces hot exhaust gases back into the intake, and on high-mileage trucks, it becomes one of the biggest maintenance headaches. That's why many owners decide to remove it along with the DPF.

EGR delete kits for 6.7 Cummins come in two general categories:

Basic Block-Off Kits

These block off the EGR ports and disable flow without removing every component. They are inexpensive, easy, and perfect for low-end DIY projects.

The average price is between $150 and $250. Ensure that the kit suits your particular truck by matching the request of the engines.

Full Replacement Kits

Full kits eliminate the EGR cooler, valves, and other hardware, and replace them with new coolant lines and blockplates. These have cleaner engine bays and enhanced long-run reliability.

They usually have prices of between $300 and $400 based on the materials, the level of machining, and the hardware provided in them.

Deleting is cheaper than the cost of a failed EGR cooler replacement in most cases, which may cost $800-1,800 with labor. That's one of the main reasons owners consider a delete in the first place.

3. Tuners & Tuning Costs

This is where most of your budget goes. The tuner controls how the truck runs after emissions components are removed.

Without proper tuning, the truck won't operate correctly, and you'll see warning lights and derates.

Popular Tuning Options

Common tuning platforms for the 6.7L Cummins include:

• EZ Lynk
• MM3
• EFI Live
• HP Tuners
• Minimax V1 Tuner

They are known for simple operation and reliable basic tuning. Each one has its own pricing structure, and not every tuner supports every model year.

Required Tuning Credits

Platforms like HP Tuners require credits to activate tuning access. When you have a custom tune, then there may also be extra charges for revision, updates, or new power levels.

Cost Range

A majority of tuners range between $500-$1,200 in hardware only. Custom tuning can be as low as 250 to as high as 1,000 dollars.

EZ Lynk easy $600-$800. MM3 advanced $700. EFI $800. HP $600. Minimaxx V1 Tuner $687.59. Minimaxx V2 Tuner $879.45

When people search cost to delete and tune a 6.7 Cummins, they are mostly looking at this combined figure.

It is possible that when you have a truck of 2022 or later model, you will require a new ECU. These can cost over $2,000 before tuning fees. That's why modern trucks have the widest price range.

4. Optional Components That Add to the Budget

The optional upgrades also enhance performance or make it easier to install.

• Full exhaust systems (turbo-back or cat-back)
• Aftermarket intake systems
• New sensors, clamps, or heat shields
• Gaskets and hardware kits

Exhaust Systems

Full $800-$1,200.

Intake Upgrades

$200-$400.

Sensors and Miscellaneous Hardware

$100-$300 gaskets.

Item	Basic Cost	Premium Cost
DPF Pipe	$300	$800
EGR Kit	$150	$400
Tuner	$500	$1,200
Options	$200	$1,000

Labor Cost to Delete a 6.7 Cummins

Labor is where many RAM truck owners get surprised. Two shops can charge very different rates for the same job.

The variation usually comes from local hourly rates, how familiar the shop is with Cummins deletes, and whether they include tuning as part of the service.

Pro labor $500-$1,500 for 6-10 hours. DIY $0 but tools $100-$300. Save $800 but risk errors.

Average Shop Labor Rates

Average prices of diesel speed shops are between $85-150 per hour. A complete full delete may take as much as 6-8 hours based on the setup.

Newer trucks between 2007.5 and approximately 2018 are in the middle range. Later trucks with modified exhaust systems or less packaging could take some extra time.

Average Labor Hours for DPF + EGR Delete

DPF 2-3 hours. EGR 3-4. Tune 1. Total 6-8.

Regional Pricing Differences

Coast $120/hour. Rural $80.

Typical Cost Ranges

$600 average. $1,200 complex.

Labor Costs by Truck Generation

Here's how labor usually compares across model years:

• 5–2012: Easiest to work on. Expect 4–5 hours of labor unless rust is severe.
• 2013–2018: More complex EGR routing. Usually 5–7 hours.
• 2019–2021: Added sensors and tighter spaces. Expect 6–8 hours.
• 2022–2026: Labor cost varies widely because many require ECU swaps and updated tuning access.

That means your labor total usually lands in the $350 to $1,100 range. When people look up the cost to delete 6.7 Cummins, they often don't factor in labor separately, but it's a major part of the final bill.

DIY Installation Cost Breakdown

Tools basic.

Tools Needed

Wrenches, jack $200 if buy.

Additional Costs to Consider

Oil $20, gaskets $50.

Cost Savings vs. Professional Install

Save $800. My DIY $100 extras.

Method	Hours	Cost	Risk
Pro	6-8	$500-$1,500	Low
DIY	8-12	$100-$300	High

Mobile Installers vs. Shop Installs

There are mobile diesel techs who offer on-site diesel delete installations. These can be cheaper because they have lower overhead, but quality varies.

If you choose a mobile installer, make sure they're experienced with Cummins trucks specifically.

The tuning portion still needs a stable connection and the right equipment, so don't choose the cheapest option without checking reviews or references.

Hidden Costs Truck Owners Often Miss

Deleting a 6.7 Cummins is not only for the first installation. Some of these behind-the-scenes factors can either increase or decrease your final cost, and once you are aware of them, it becomes a lot easier to draw up a realistic budget.

Hidden: Tuning credits $100-$300, shipping $50-$200, broken bolts $50-$200, shop fees $100.

1. Model Year Compatibility

Your model year affects everything: tuning options, ECU compatibility, pipe routing, sensor count, and more.

• Older models (2007.5–2012)are the cheapest to delete.
• 2013–present trucks have more emissions layers and are more expensive.
• 2022+ models may require ECU replacements costing more than the delete kits themselves.

This is one of the top reasons owners see huge price variations for deleting a 6.7 cummins.

2. ECU Unlock Requirements

Some years need an "unlocked" or replacement ECU before tuning will work. These often add:

• $400–$800 for an unlock
• $1,200–$2,500+ for a replacement ECU (2022+ models)

This alone can double the total cost.

3. Exhaust Configuration

If your current exhaust is rusted, seized, or damaged, removal takes longer. Some shops charge extra if they have to cut out old components.

4. Tuning Complexity

Multi-map tuning, transmission tuning, and custom revisions cost more. A simple tune with one power level is cheaper, but most owners prefer tuners that give multiple options like tow, daily, and performance modes.

5. Location-Based Price Fluctuations

Diesel shops in cities or high-cost states typically charge more. Small diesel performance shops and rural areas tend to be very inexpensive.

Repairing vs. Deleting a 6.7 Cummins: Which Is Cheaper?

A lot of Cummins engine owners consider deleting because a single emissions component has failed.

Repair DPF $2,000-$3,000, EGR $1,000-$2,000, DEF $500-$1,000. Delete saves $3,000-$6,000 long-term.

To see which option makes financial sense, here's a quick comparison.

Common Repair Costs

• DPF replacement: $2,000–$3,000
• SCR replacement: $1,000–$3,000
• DOC replacement: $700–$2,000
• EGR cooler replacement: $1,000–$2,000
• NOx sensor(s): $200–$600 each
• DEF system repairs: $500–$1,000+

When two or more components break down simultaneously, the cost of repair may reach up to 3,000 to 6,000 dollars easily.

Long-Term Maintenance Cost Savings After Deleting

Reduced Soot Buildup

Oil clean, changes less.

Fewer Regeneration-Related Failures

No $500 cleans.

Lower Operating Cost Over Time

$1,000/year saved.

Repair	Cost	Delete Save
DPF	$2,500	$2,000
EGR	$1,200	$1,000
DEF	$800	$500
Annual	$1,000	$800

When Repairs Make More Sense

Although deleting may be cheaper, it may not be the best in some cases:

• In case your truck is still in warranty.
• In case you require the truck to be registered in a state where there are emissions tests.
• In case you intend to sell the truck in the near future.
• If your model supports cost-effective repairs (rare on newer models)

When Deleting Makes More Sense

Deleting tends to be the better financial choice when:

• You're outside warranty
• You have repeated emissions failures
• You use the truck for off-road, farm, or private property use
• You're facing a large repair quote (EGR cooler + DPF + sensors, etc.)

In most cases, if the repair bill is over $2,500, a delete becomes the cheaper long-term option.

Legal, Emissions, and Warranty Considerations

Every owner needs to be clear on this part: deleting emissions systems is illegal on public roads in the United States, Canada, and many other regions.

It violates federal environmental laws and voids factory warranties.

Illegal on-road USA. Fines $5,000-$37,000. Voids warranty. Off-road ok.

What This Means for You

• Your truck becomes "for off-road use only" in the eyes of the law.
• You may not pass state emissions checks.
• Dealers can reject warranty repair that has nothing to do with emissions.
• Some enforcing states are more stringent than others.

Selling a Deleted Truck

Selling a deleted truck can be tricky. It is acceptable to some buyers, but not to dealers and mainstream buyers.

2026 EPA strict. My off-road only. Revert $5,000. Rules vary state. CA no. TX maybe.

Countries and states have their own laws that govern the sale and buying of a deleted vehicle, which is why it is always advisable to see what your regional laws state before selling or buying a deleted vehicle.

Is Deleting a 6.7 Cummins Worth the Cost?

Removing a 6.7 Cummins is a massive move, and the owners tend to want to know whether the benefits are, in fact, worth the cost.

Worth off-road: +30-80 HP, lower temps, longer life. 1-3 MPG gains. Legal risks high.

The solution, in most instances, will be based on the state of your truck, the type of its usage and the cases of repeated emissions.

When it is performed properly and within the appropriate setting, several owners report instant driveability and fuel economy along with a significant increase in reliability.

Performance Benefits and Fuel Economy Improvements

Most owners don't delete just to avoid costly repairs. A properly tuned and deleted truck may run with increased efficiency and smoothness as compared to its stock version, particularly with an increase in mileage.

1. Horsepower and Torque Improvements

A proper tune after deleting often gives the truck a noticeable bump in power. Most mild setups add around 40–80 hp, and even though that doesn't turn the truck into a race build, the throttle response and pulling strength feel smoother.

2. Lower Exhaust Temps

Removing restrictive components reduces backpressure, which drops EGTs. This is especially helpful if you tow. Lower exhaust temps generally mean less strain on the turbo and other heat-sensitive parts.

3. Engine longevity

A cleaner intake path, more stable temps, and fewer forced regens can help reduce long-term wear. That's one reason many high-mileage owners report that their trucks simply "run easier" after a delete.

4. Typical MPG gains after deleting

Most owners see a bump of 1–3 mpg once everything is tuned and running properly. The improvement comes from smoother airflow, a more efficient burn, and the removal of regen cycles that normally waste fuel.

5. Cleaner Intake System

To improve long-term reliability, an EGR delete can prevent the occurrence of soot in the intake and valves.

If you use the truck in environments where deletes are permitted and you're facing high repair bills, it can save thousands in the long run.

Proprietors who pull heavy loads tend to experience improved functioning and cut down on emission-associated challenges.

Real-world Examples

Daily drivers often report moving from the mid-teens to the high-teens in hand-calculated mileage. Trucks that tow regularly tend to see the biggest gains since they're no longer fighting high exhaust temps or frequent regens on long pulls.

Frequently Asked Questions

How much horsepower does a deleted 6.7 Cummins gain?

Most mild tunes add 40–80 hp. More aggressive tunes can go higher, but longevity becomes a factor. The point of a delete isn't maximum horsepower. It's a smoother operation and reduces stress on components.

Do you need a tuner after deleting?

Yes. A tuner is required to keep the truck running properly after removing emissions parts. Without it, the truck will throw codes, run poorly, and eventually derate.

Do deletes increase resale value?

Usually no. Some private buyers may prefer a deleted truck, but dealerships and many states won't touch them due to emissions laws.

What's the cheapest way to delete a 6.7 Cummins?

A DIY setup using a budget delete pipe, an affordable EGR block-off kit, and an entry-level tuner. Most people can get it done for $450–$950.

How much does it cost to delete a 2014 Cummins?

Most fall between $1,500 and $2,500 with a standard shop install. DIY versions are usually under $1,000.

Can you delete only the DPF and leave the EGR?

It's possible, but not recommended. Leaving the EGR active still sends soot into the intake, and the truck won't run as clean or reliably. Most owners delete both at the same time.

How long does a full delete take?

Around 4–8 hours, depending on the truck's model year, condition, and whether the shop has to deal with rusted components.

Does deleting really improve mileage?

Yes, usually by 1–3 mpg. Some owners see higher gains, but that depends on driving style, tune quality, and load.

Will tuning damage the engine?

Not if done correctly. Quality tuners stay within safe parameters. Problems usually come from extreme "race" tunes that push too much torque at low rpm.

Can a deleted truck be returned to stock?

Yes, but it can be expensive. You'll need all emissions parts reinstalled, sensors replaced, and the factory tune reloaded.

How many miles will a deleted 6.7 Cummins last?

Plenty reach 300k+ when tuned safely and maintained well. The delete itself doesn't shorten lifespan unless paired with aggressive “hot” tunes.

Can I pass emissions testing with a deleted EGR system?

No. A deleted truck won't pass emissions in states or regions that require testing.
