Ford 6.7 Powerstroke DPF Delete Race Pipe Exhaust Overview

Most post-2007 diesel vehicles like the Ford 6.7 Powerstroke come equipped with a DPF (Diesel Particulate Filter) to meet emissions standards, but these systems often lead to higher backpressure, reduced fuel economy, and increased maintenance costs.

Installing a 6.7 Powerstroke delete pipe—also known as a straight pipe—removes these restrictions, boosting exhaust flow and MPG. When choosing between 4" or 5" pipes, the 5 inch straight pipe delivers a deeper tone with less drone, making it a top choice for towing and performance builds.

Benefits of the Ford 6.7 Powerstroke DPF Delete Pipe

Expect to see a significant increase in fuel mileage. If your DPF is plugged up your probably averaging about 13-14 mpg. More or less depending on the severity of the restriction. After deleting the DPF/CAT expect to get a combined mileage of 18-19 mpg.

• It removes the need to service the DPF at regular intervals (cleaning, replacement)
• A DPF delete will remove the possibility of a DPF failure which could cause expensive diesel repairs
• Due to less exhaust backpressure, the DPF delete increases exhaust flow and therefore increases the performance of your motor!
• Paired with an ECU remap, the DPF delete is proven to increase power and torque for all vehicles

Ford 6.7 Powerstroke DPF Delete Pipe Installation

Install takes about 1hr with basic hand tools done on the ground of your driveway or garage. Quicker if you have automotive style lift. Cutting may be be required to fit shorter wheelbase bed/cab configurations. Clamps, hangers and hardware are included. You may have to re-use some factory hardware.

Tuner Required for DPF Delete Pipe Installation

Installing a 6.7 Powerstroke delete pipe requires more than just swapping out hardware. When removing of the DPF, CAT, SCR, and/or DOC involves removing and eliminating emission related sensors. A DPF delete capable tuner is required to prevent any check engine light or diagnostic trouble codes from setting.

4" vs 5" Straight Pipe Comparison

When choosing a 6.7 Powerstroke delete pipe, the most common options are 4-inch and 5-inch straight pipes.
The 4-inch straight pipe delivers a tighter, raspier exhaust note—especially noticeable at lower RPMs—making it ideal for daily driving or mildly tuned setups where excessive drone is undesirable.
In contrast, the 5 inch straight pipe 6.7 Powerstroke offers a deeper, more refined tone with less high-pitch resonance. It excels in high-output builds and towing scenarios, where increased exhaust flow is beneficial.

Driver feedback suggests:

• 4" straight pipe is great for stock-to-lightly-modded trucks and a quieter cabin

• 5" straight pipe is perfect for aggressive builds, deeper tone lovers, or anyone maximizing exhaust performance

Ford 6.7 Powerstroke DPF Delete Pipe FAQs

Q1: What is a DPF Delete Race Pipe, and what does it do?
A1: A DPF (Diesel Particulate Filter) Delete Race Pipe replaces the factory DPF, eliminating exhaust restrictions to improve airflow, boost performance, and reduce backpressure. This modification typically increases horsepower, torque, and fuel efficiency while preventing future DPF-related issues (e.g., clogging, regeneration failures).

Q2: Is a DPF Delete legal for street use?
A2: No. Removing the DPF violates U.S. EPA and CARB emissions regulations. This modification is intended for off-road/racing use only. Fines and penalties may apply if used on public roads. Always check local laws before installing.

Q3: Will I need a tuner after installing a DPF Delete Pipe?
A3: Yes. The 6.7L Powerstroke’s ECU requires a compatible DPF-off tune to prevent check engine lights and ensure proper engine operation. Running a delete pipe without tuning can cause performance issues or damage.

Q4: Does the 4" or 5" diameter affect performance?
4": Better for stock or mildly tuned trucks, balancing flow and backpressure.
5": Ideal for high-horsepower builds (500+ HP), reducing restriction but may require supporting mods (e.g., turbo upgrades).

Q5: Will deleting the DPF void my warranty?
A5: Yes. Dealerships can detect DPF deletes and may deny powertrain warranty claims. Proceed at your own risk.

Q6: How difficult is the installation?
A6: Installation is straightforward for experienced DIYers but requires lifting the truck and removing the OEM DPF/catalytic converter. Professional installation is recommended if you lack tools/experience.

Q7: What are the maintenance benefits of a DPF Delete?
No more costly DPF cleanings/replacements.
Eliminates regeneration cycles, saving fuel.
Reduces EGTs (exhaust gas temperatures) under heavy load.

Q8: Can I pass emissions testing with a DPF Delete?
A8: No. Removing emissions equipment will cause your truck to fail smog tests in regulated states.

Q9: Does the race pipe produce louder exhaust noise?
A9: Yes. Deleting the DPF and muffler (if applicable) increases exhaust volume. Adding an aftermarket muffler can reduce drone if desired.

Q10: Will a 6.7 Powerstroke delete pipe trigger a check engine light?
A1: Yes—unless paired with a proper DPF-delete tune. The stock ECU will detect missing emissions equipment and trigger a CEL. A tuner with DPF-off support is required.

Q11: Should I choose a 4" or 5" straight pipe?
A2: A 4" pipe is ideal for daily drivers and minimal drone. The 5 inch Powerstroke straight pipe delivers a deeper tone and higher flow, perfect for towing or performance setups.

Q12: Will fuel economy improve after installing a delete pipe?
A3: Typically, yes. With lower exhaust restriction, many users report a gain of 13-14 MPG on average.

Q13: Can I still pass emissions testing?
A4: No. This product is for off-road or race use only. It is not compliant with EPA/CARB regulations and will not pass emissions testing in most states.

Q14: Will it be too loud?
A5: That depends on pipe size and whether you use a muffler. 4" is moderately loud; 5" has a deeper tone. A resonator or muffler can reduce in-cab drone significantly.
