What is a 6.7L Powerstroke Delete Kit
A 6.7L Powerstroke delete kit is a performance package that removes or bypasses the truck’s stock emissions hardware (like the DPF, DOC, EGR, and DEF/SCR systems) to free up exhaust flow and simplify the engine. They are designed to give the 6.7L Powerstroke improved breathing and reliability.
Why Owners Remove (Delete) Their 6.7L Powerstroke
Truck owners choose to delete emissions components for several practical benefits:
- More Power and Torque: Removing the DPF/EGR restrictions lets the turbo work more freely, yielding noticeably higher horsepower and torque under load.
- Better Fuel Economy: With less backpressure and no frequent DPF regens, many owners see a fuel-mileage gain of roughly 2–5 MPG. Of course, actual savings depend on driving style and load.
- Lower Maintenance Costs: Without a DPF or EGR system, you eliminate expensive repairs. For example, a failed DPF can cost $2,000–4,000 to replace.
- Improved Reliability: Emissions parts (especially the EGR cooler, sensors and DPF) are common failure points. Deleting them removes those failure modes.
- No More Limp Mode/Warning Lights: A deleted truck (with the proper tune) will rarely see “DPF regen” or “exhaust system” limp modes.
Together these benefits make delete kits popular for heavy-duty use. Many owners who tow or work their trucks daily prefer having uninterrupted power and avoiding costly emissions repairs.
What Parts Are Deleted? Typical 6.7L Delete Kit Configurations
Full All-in-One Delete Kit (DPF, DEF, DOC, EGR Delete + Tuner)
A complete delete kit for a 6.7L Powerstroke removes virtually the entire emissions system. This usually includes: a stainless-steel downpipe/DPF delete pipe (replacing the factory DPF and often the DOC), block-off plates for the EGR valve and cooler, removal or blanking of the DEF tank components, and high-flow pipes or mufflers. The kit also comes with an ECU programmer or calibrations (“tunes”) that disable all the factory emissions logic (EGR, DPF regens, DEF injection, NOx sensors, etc.). In effect, the trucks can run without any emissions hardware installed.
These kits are suited for owners who want one-stop performance and reliability gains.
DPF + DEF/SCR Delete Kit
A DPF/DEF-only delete kit focuses on removing the particulate filter and disabling the urea/SCR system. In practice this means installing a straight (race) pipe or downpipe in place of the DPF, and usually the small DOC, since on many 6.7L trucks the DPF housing contains the DOC, and reprogramming the ECU to turn off the DEF injector and related sensors.
The kit typically includes the delete pipe, replacement gaskets, clamps and hardware to bolt into the exhaust, and tuning support. Some versions include a high-flow muffler or keep the stock muffler for quieter operation.
This partial delete is aimed at owners who want to eliminate DPF/regeneration hassles and DEF fluid fills but aren’t addressing the EGR system.
EGR Delete Only
An EGR delete kit removes just the Exhaust Gas Recirculation system.
It typically includes precision-machined block-off plates for the EGR valve and cooler, new coolant and vacuum lines (or caps for the old lines), plus gaskets and hardware. The kit may also include a bypass for the EGR cooler coolant flow. It stops any exhaust from recirculating into the intake. A tune is used to disable the EGR operation in software and also prevent the error code.
This option is for owners who want cleaner intake air and less carbon buildup inside the engine. Deleting the EGR improves throttle response and longevity.
Tune-Only (Software Delete)
Finally, some owners opt to use only an ECU tuner or programmer, without physically removing parts. Some tuners can disable emissions systems in software, for example turning off the EGR or SCR logic and skipping DPF regen cycles.
Some tuner companies market a “DEF delete” mode (just removing the need to add urea) or an “EGR off” tune. Popular tuning products for the 6.7L include offerings from Edge, DiabloSport, SCT/Bully Dog, GDP/EZ Lynk, H&S, and others. These often come with pre-loaded tuning profiles to eliminate DPF/EGR codes. Some high-end tuners also offer optional transmission (TCM) tunes, though not all tuners support that.
Summary: In most discussions, a generic “6.7 Powerstroke delete kit” usually means the full all-in-one kit – i.e. hardware deletes for the DPF, DOC and EGR, plus a performance tune that disables DEF/SCR. This complete bundle gives the largest power and reliability gains.
How to Choose the Right 6.7 Powerstorke Delete Kit
Compatibility
Make sure the kit matches your truck’s exact model, year and configuration. The 6.7L Powerstroke has seen changes over the years, variable cab size, bed length, 4×2 vs 4×4, and especially the 2017 Gen3 update and the 2020+ chassis with 10-speed transmission. Some kits are specific to model-year ranges (2011–Early 2015, 2015.5-2016, 2017–2019, 2020–Now, etc.) or even to Cab & Chassis versus pickup. Always check fitment carefully. If you plan to reprogram the transmission, note whether the kit/tuner supports your TCM or any manufacturer lockouts (“SOTF”) on tuning.
Delete Scope
Decide how much you want to remove. A all-in-one kit delivers the biggest benefits but costs more. Choose based on your goals and legal tolerance.
Build Quality
Look for high-quality materials. Stainless-steel pipes and CAT-less downpipes resist corrosion and heat. Precision CNC-cut block-off plates and thick gaskets ensure a good seal. A kit should include robust clamps and hardware. Avoid flimsy or thin components.
Tuner Support
Check whether a tuner/programmer is included or recommended. If not included, ensure compatibility with a reputable tuner. Remember that a delete is useless without a tune. Also see what tuning levels are available (daily drive, towing, performance).
Customer Support
Finally, consider the seller’s reputation and support. A knowledgeable supplier should provide clear instructions and be available to help with fitment questions. They should help with installation guides and tuning instructions.

Installation Tips for Deletion
DIY vs Professional: Installing a delete kit can be labor-intensive. A full kit involves removing the front or full exhaust, EGR components, and making coolant/vacuum modifications. Inexperience can lead to leaks or wiring mistakes. If you decide to DIY, set aside a full day, and have proper tools.
Key Constructions: Pay extra attention to sealing and sensor plumbing. Any block-off plate must be leak-tight, do use new high-temp gaskets and tighten bolts to spec. EGR coolant lines that are removed should be capped or rerouted properly to avoid coolant leaks. Keep any removed sensors or pipes, you may need them if you ever revert. Check all clamps and welds on the delete pipe. After installation but before starting, double-check that all electrical connectors on the old DEF/EGR solenoids are unplugged or removed to prevent shorts.
Tuning Integration: A proper tune will disable all related fault codes. Many kits will have you install first, then plug in the tuner and flash right away. Always follow any instructions from the tuner provider.
FAQ
Q: Will deleting the DPF/EGR void my warranty?
Yes. Dealers can detect a delete and will almost always deny any warranty claims on an engine or emissions components once it’s removed. Any delete is done at your own risk from a factory warranty perspective.
Q: Is a delete kit street-legal?
No. In the U.S., it’s illegal to operate a vehicle on public roads with disabled or removed emissions systems. Delete kits are intended for racing or off-highway use only. As the EPA states, “the Clean Air Act prohibits tampering with emissions controls”. Only use a delete kit on private property or racetracks where emissions laws don’t apply.
Q: How much does a complete delete kit cost?
A full all-in-one delete kit with tuner typically costs around $1,500–3,000 depending on vendor and what’s included.
Q: Does deleting improve engine reliability?
In most cases, yes. Dyno tests and owner reports that removing the DPF/EGR makes the engine more reliable in the long run, because clogging, soot buildup and failed sensors are eliminated. Of course, this assumes the delete is done correctly with proper coolant reroutes and tune.
Q: Do I need an ECU tune after installing a delete?
Absolutely. A delete kit must be accompanied by an ECU tune or programmer. If you simply remove hardware and do not reprogram, the truck will throw codes, go into limp mode, or not run properly.
Q: Will a delete kit improve fuel economy?
Many owners see a modest MPG gain after deleting, especially on the highway or under load. Less backpressure and no unburned fuel from regen cycles tends to improve efficiency. One study of highway driving showed stock trucks at ~15–16 MPG versus ~19–21 MPG after DPF removal (a 2–5 MPG improvement in practice). While real-world results vary (load, tuning level, etc.), it’s common to save a few miles per gallon. Just remember this only applies when you’re not idling or city driving; the biggest gains are at steady speeds or when towing.
Final Thoughts
Choosing the right 6.7 Powerstroke delete kit comes down to compatibility, build quality, tuning support, and your performance goals. With the right setup and proper installation, owners can achieve smoother performance and fewer maintenance issues. Use this guide as a clear starting point before making your purchase.
