6.7 Delete Kit: Complete Buying Guide

A 6.7 delete kit may refer to a DPF exhaust pipe, EGR cooler kit, throttle-valve replacement, CCV reroute, or a combination of these components. To choose the right kit, first identify whether your truck has a Ford 6.7L Power Stroke or a Ram 6.7L Cummins. Then confirm the model year, chassis type, exhaust configuration, and intended use.

Although Ford and Ram both offer 6.7L diesel engines, their parts are not interchangeable. Pickup and Cab & Chassis versions of the same truck may also require different hardware.

Quick Answer: How Do You Choose the Right 6.7 Delete Kit?

Choose a 6.7 delete kit by confirming five details:

1. Engine: Ford 6.7L Power Stroke or Ram 6.7L Cummins.

2. Model year: Production changes affect sensors, flanges, coolant routing, and mounting points.

3. Chassis: Pickup or Cab & Chassis.

4. System: DPF, EGR cooler, throttle valve, CCV, or multiple systems.

5. Vehicle use: Verify that the planned modification is legal for its intended application.

Do not order by engine displacement alone. A part advertised simply for a “6.7 diesel” may not match your truck.

What Is Included in a 6.7 Delete Kit?

“Delete kit” is a broad retail term rather than a standardized package. Some kits contain one exhaust pipe, while others include plates, hoses, fittings, clamps, brackets, or several system-specific parts.

“Complete” does not always mean every component required for installation. Check the written parts list before ordering.

Ford Power Stroke vs. Ram Cummins Fitment

The first buying decision is whether the truck uses a Ford Power Stroke V8 or a Cummins inline-six.

These engines share a 6.7L displacement but use different intake, exhaust, cooling, and electronic systems.

The model-year range in a product title is only a starting point. Confirm the VIN, production date, truck model, chassis, cab, bed, and wheelbase before placing an order.

6.7L Power Stroke Delete Kit Options

Ford 6.7L Power Stroke DPF Pipe

Ford Super Duty owners can compare the available 2011–2025 6.7L Power Stroke 4-inch and 5-inch DPF delete pipe options.

Before choosing a pipe, confirm:

• Exact model year

• F-250, F-350, F-450, or F-550

• Pickup or Cab & Chassis

• Cab and bed length

• Wheelbase

• Pipe diameter

• Muffler configuration

• Included clamps and hangers

• Filter-replacement or downpipe-back layout

A product page covering 2011–2025 may offer several configurations. Not every option will fit every truck within that range.

Ford Power Stroke CCV Reroute

A CCV modification is different from a DPF or EGR modification. It changes how crankcase vapors are separated or routed away from the intake system.

The 2011–2025 6.7L Power Stroke CCV reroute/delete kit is designed for Ford 6.7L applications.

When comparing CCV kits, look for:

• Oil-separation design

• Heat-resistant hoses

• Secure sealing surfaces

• Drain requirements

• Vent routing

• Sensor compatibility

• Crankcase-pressure management

• Clear maintenance instructions

A CCV reroute is not a full DPF or EGR delete kit. These systems should be evaluated separately.

Ford Power Stroke EGR and Cooler Kit

Ford changed the 6.7L Power Stroke platform during its production run. The 2011–2014 and 2017–2025 Power Stroke EGR cooler delete upgrade kit specifically identifies those model-year groups.

The gap in fitment matters. Owners of 2015–2016 trucks should use a kit explicitly designed for those years rather than assuming that an earlier or later kit will fit.

Before ordering, check for:

• Correct block-off plates

• Application-specific gaskets

• Coolant bypass components

• Sensor or probe provisions

• Corrosion-resistant materials

• Complete mounting hardware

• High Output engine compatibility

• Pickup or Cab & Chassis fitment

Any work involving the cooling system must preserve correct coolant flow. Follow the manufacturer’s instructions and use a qualified technician when necessary.

6.7L Cummins Delete Kit Options

2019–2025 Ram 6.7L Cummins DPF Pipe

Owners of newer Ram Heavy Duty pickups can compare the 2019–2025 Ram 6.7L Cummins 4-inch and 5-inch DPF pipe configurations.

Confirm whether the selected option matches a Ram 2500 or 3500 pickup. Do not assume that a pickup exhaust will fit a commercial Cab & Chassis truck.

Important fitment details include:

• Crew Cab or Mega Cab

• Short bed or long bed

• Wheelbase

• Four-inch or five-inch diameter

• Straight-pipe or muffled design

• Filter-replacement or downpipe-back layout

• Required cutting or trimming

• Included clamps and hangers

2013–2018 Ram 6.7L Cummins DPF Pipe

Fourth-generation Ram trucks use a different exhaust arrangement from later models. The 2013–2018 Ram 6.7L Cummins DPF delete pipe is intended for this earlier generation.

Do not substitute a 2019–2025 pipe simply because both trucks use a 6.7L Cummins. Exhaust routing, mounting points, sensor locations, and aftertreatment layouts may differ.

Verify the truck’s year, cab, bed, wheelbase, pipe layout, and chassis before choosing an option.

2007.5–2024 Cummins Throttle-Valve Delete

The 2007.5–2024 Ram 6.7L Cummins EGR throttle-valve delete kit replaces the factory throttle-valve section of the intake.

This is a component-specific product. It should not be confused with a complete EGR cooler kit.

Determine whether your project requires:

• Throttle-valve components only

• EGR valve hardware

• EGR cooler hardware

• Coolant rerouting parts

• Intake gaskets

• Additional mounting hardware

Confirm whether the product supports standard pickups, Cab & Chassis trucks, or both.

2013–2023 Ram Cab & Chassis EGR Kit

Commercial Ram trucks require special attention. The 2013–2023 Ram 6.7L Cummins Cab & Chassis EGR delete kit is intended for Cab & Chassis applications rather than standard pickups.

Cab & Chassis trucks can have different cooling layouts, exhaust routing, frame dimensions, and equipment placement.

Confirm whether the vehicle is a:

• Ram 3500 Cab & Chassis

• Ram 4500 Cab & Chassis

• Ram 5500 Cab & Chassis

A standard Ram 2500 or 3500 pickup kit should not be used unless the manufacturer explicitly confirms compatibility.

2007.5–2009 Ram 6.7L Cummins EGR Kit

Early 6.7L Cummins trucks use their own emissions-system configuration. Owners should review the 2007.5–2009 Ram 6.7L Cummins EGR delete kit.

The “2007.5” distinction is important because diesel engines and emissions systems can change during a model year. Use the VIN, production date, and vehicle emissions label to confirm the engine family.

Do not assume that a kit designed for a 2010 or newer Cummins will fit a 2007.5–2009 truck.

4-Inch vs. 5-Inch Exhaust

A four-inch exhaust is generally the practical choice for a stock or moderately modified truck. It is easier to route, usually lighter, and may produce less cabin drone.

A five-inch exhaust is commonly selected for a deeper sound or a higher-output competition build. It requires more clearance and may be louder inside the cab.

Pipe diameter alone does not guarantee more horsepower, lower exhaust temperatures, or better fuel economy. Results depend on the complete engine setup, turbocharger, calibration, load, gearing, tires, and driving conditions.

Choose the diameter according to physical fitment and the goals of the complete build—not the assumption that bigger is always better.

Does a 6.7 Delete Kit Require Tuning?

Physical changes to DPF or EGR systems can affect the sensors and diagnostic strategies monitored by the engine control module. Incompatible hardware and software may cause:

• Check-engine lights

• Diagnostic trouble codes

• Engine derating

• Limp mode

• Starting problems

• Poor drivability

• Unexpected exhaust behavior

However, software designed to disable required emissions monitoring may itself be illegal. Confirm that the vehicle and application are lawful before purchasing hardware or calibration services.

A CCV reroute may not require the same electronic changes, but compatibility depends on the kit design. Follow the manufacturer’s instructions and consult a qualified diesel technician.

What Makes a Good 6.7 Delete Kit?

A quality kit should be judged by construction, fitment documentation, completeness, and support rather than dramatic performance claims.

Durable Materials

For exhaust components, look for:

• Clearly identified pipe material

• Consistent mandrel bends

• Clean welds

• Adequate wall thickness

• Corrosion-resistant surfaces

• Strong hangers and clamps

For engine-bay components, look for:

• Heat-resistant hoses

• Durable fittings

• Application-specific gaskets

• Corrosion-resistant plates

• Secure mounting hardware

• Properly machined sealing surfaces

Clear Fitment Information

A useful product listing should identify:

• Engine

• Model years

• Supported truck models

• Pickup or Cab & Chassis fitment

• Cab and bed limitations

• Wheelbase requirements

• Pipe diameter

• Muffler configuration

• Sensor and flange details

• Factory hardware that must be reused

Avoid buying a product when the listing provides only a broad engine name without vehicle-specific fitment details.

Complete Parts List

Compare the product photographs with the written contents. Check for:

• Pipes

• Plates

• Gaskets

• Clamps

• Hangers

• Bolts

• Hoses

• Fittings

• Brackets

• Instructions

A lower-priced kit may cost more overall if essential installation parts must be ordered separately.

Installation Support

Look for clear instructions, vehicle-specific guidance, accessible customer support, and a written warranty.

Many product warranties cover manufacturing defects but exclude labor, corrosion, incorrect installation, altered parts, or damage to the vehicle. Read the warranty before installation.

Costs Beyond the Kit Price

The hardware price is only part of the total cost. A realistic budget may also include:

• Professional labor

• Replacement gaskets

• One-time-use fasteners

• Additional clamps or adapters

• Coolant and service fluids

• Diagnostic work

• Lawful competition-vehicle support

• Future maintenance

• Factory-system restoration

• Inspection costs

• Warranty implications

Keep the original components when lawful and practical. A future owner, inspection program, or change in vehicle use may require the factory system to be restored.

Common Buying Mistakes

Ordering by “6.7L” Alone

Ford Power Stroke and Ram Cummins engines share the same displacement designation, but their parts are not interchangeable.

Ignoring Cab & Chassis Fitment

Commercial chassis models may use different exhaust, cooling, and mounting arrangements from standard pickups.

Assuming Every Kit Is Complete

A DPF pipe does not automatically include EGR or CCV components. A throttle-valve kit is not necessarily a complete EGR kit.

Overlooking Model-Year Breaks

Important examples include:

• Ford 2015–2016 EGR configurations

• Ford 2011–2014 versus 2017–2025 EGR fitment

• Ram 2013–2018 versus 2019–2025 exhaust layouts

• Early 2007.5–2009 Cummins EGR systems

Choosing the Wrong Exhaust Layout

A short filter-replacement pipe is different from a downpipe-back or turbo-back system. Review the product photographs, dimensions, and parts list.

Buying Based on Performance Claims

Horsepower and fuel-economy results vary. Give more weight to material specifications, fitment, measurements, installation quality, and controlled test data.

Treating “Off-Road Only” as a Legal Exemption

Product labeling does not override federal, state, provincial, or local law. Verify the legality of the part, installation, vehicle, and intended use before buying.

Frequently Asked Questions

What does a 6.7 delete kit include?

It depends on the product. A 6.7 delete kit may include a DPF pipe, EGR plates and coolant fittings, a throttle-valve replacement, a CCV reroute, or several components. Check the written contents before ordering.

Is a Ford 6.7 delete kit compatible with a 6.7 Cummins?

No. Ford’s 6.7L Power Stroke and Ram’s 6.7L Cummins use different engines, intake systems, exhaust layouts, cooling systems, and electronics.

Is a 6.7 delete kit legal for street use?

Removing or disabling factory emissions controls is generally illegal for vehicles operated on U.S. public roads. Other countries, states, and provinces may have additional rules. Consult the appropriate regulator before purchase or installation.

Is a CCV reroute the same as a full delete kit?

No. A CCV reroute changes the crankcase ventilation path. It does not replace the DPF exhaust section or the EGR cooler.

Do pickup kits fit Ram Cab & Chassis trucks?

Not necessarily. Cab & Chassis models may require application-specific exhaust, EGR, and cooling components. Only use a pickup kit if the manufacturer confirms the exact chassis is compatible.

Should I choose a 4-inch or 5-inch exhaust?

A four-inch system is generally easier to fit and suitable for many moderate builds. A five-inch system is commonly selected for a deeper sound or a high-output competition application. Confirm available clearance before deciding.

Can a 6.7 delete kit improve fuel economy?

Results are not guaranteed. Any change may depend on the vehicle’s condition, calibration, load, gearing, tires, driving style, and previous system performance. Avoid relying on a fixed MPG claim without controlled test data.

Does every DPF pipe include a muffler?

No. Some products are straight pipes, while others include or support a muffler. Select the exact configuration shown on the product page.

Why does wheelbase matter?

Wheelbase, cab, and bed length can change the required exhaust-pipe length and hanger locations. Some systems may require trimming or an extension.

How can I confirm fitment?

Record the VIN, engine family, production date, chassis type, cab, bed, wheelbase, and current exhaust diameter. Compare these details with the listing or request written confirmation from the seller.

Conclusion

The best 6.7 delete kit is not simply the largest pipe or the package with the broadest model-year range. It is the product that matches the exact engine, production year, chassis, exhaust layout, component scope, and lawful intended use.

Start by separating Ford Power Stroke applications from Ram Cummins applications. Then determine whether the project involves the DPF, EGR cooler, throttle valve, CCV system, or several components.

Careful fitment verification helps prevent incompatible parts, installation delays, and unexpected costs. Legal verification should always happen before the purchase.
