What's a 6.4 Powerstroke Delete Pipe?
A 6.4 Powerstroke Delete Pipe is a straight-through exhaust pipe designed to physically remove and replace the factory Diesel Particulate Filter (DPF), commonly referred to as adelete pipe.
This DPF delete pipe replaces the stock DPF, significantly improves exhaust flow, reduces backpressure, and allows the engine to operate more efficiently.
6.4 Powerstroke Delete Pipe Materials & Quality
Our 6.4 Powerstroke Delete Pipes are built for durability and performance.
Available Features:
- Mandrel-bent tubing for smooth exhaust flow
- 4'' and 5'' diameter options

- Optional sensor bungs (model-dependent)
Every pipe is designed to withstand high temperatures and harsh diesel conditions.
Key Benefits of Installing a 6.4 Powerstroke Delete Pipe
- Reliability: Eliminate the DPF to prevent limp mode and sensor-related breakdowns.
- Fuel Efficiency: Stop fuel-wasting regen cycles to get more miles from every tank.
- Engine Longevity: Reduce backpressure to extend the life of your turbo and engine.
- Better Cooling: Significantly lower EGTs by removing restrictive factory filters.
- Performance: Experience much faster turbo spooling and smoother throttle response.
6.4 Powerstroke Delete Pipe: Deleted vs. Stock
| Dimension |
Stock Exhaust |
Delete Pipe |
| Horsepower |
Rated at 350 HP; performance is often choked by extreme exhaust backpressure. |
Increased; With the DPF removed and a tuner, gains of 50–250+ HP are common. |
| Fuel Economy |
Poor; The 6.4 is notorious for frequent regen cycles that dump raw fuel into the exhaust. |
Improved; Removing the DPF and stopping regens typically results in a 3–5 MPG increase. |
| Maintenance Cost |
Very High; Frequent DPF cleanings and fuel-diluted oil changes are required. |
Reduced; Eliminates expensive emissions sensors and the need for frequent DPF maintenance. |
| Reliability |
Low; Cylinder washing (from fuel in oil) and DPF clogs frequently lead to engine failure. |
Significantly Enhanced; Stops fuel dilution in oil and removes the primary causes of engine stress. |
| Exhaust Gas Temp |
Extremely High; The DPF acts as a heat trap; EGTs spike dangerously during regeneration. |
Lower EGTs; High-flow piping allows the turbo to breathe, dropping temps by 200°F+. |
| Legal Status |
Street Legal; EPA compliant. |
Off-Road / Competition Use Only. |
| Exhaust Flow |
Highly Restricted; The dense DPF and CAT core create a massive bottleneck for exhaust. |
Maximum; A straight-through pipe allows exhaust to exit freely, reducing engine strain. |
| Backpressure |
Extreme; Excessive pressure builds up against the turbos, leading to premature wear. |
Minimal; Virtually eliminates backpressure, allowing for faster turbo response and longevity. |
| Sound |
Very Quiet; The massive DPF assembly effectively muffles almost all turbo and engine sound. |
Powerful; Unlocks a loud, aggressive hiss and deep exhaust note unique to the 6.4. |
| Supports Tuning |
Only supports mild, emissions-compliant tuning. |
Required; Must be paired with a tuner to bypass the complex DPF pressure sensors. |

How to Install a 6.4 Powerstroke Delete Pipe
Installing a 6.4L Powerstroke Delete Pipe (2008–2010) replaces the factory Diesel Particulate Filter (DPF) section of the exhaust with a high-flow pipe to reduce backpressure, lower exhaust gas temperatures (EGTs), and eliminate regeneration-related issues.
Installation Steps
- PCM Preparation & Tuning: Before removing any exhaust hardware, the PCM is updated using a supported tuner. This disables regeneration cycles and emissions-related diagnostics, preventing limp mode once the DPF is removed.
- Factory DPF Exhaust Removal: The factory exhaust section containing the DPF and Diesel Oxidation Catalyst (DOC) is unbolted and removed. Exhaust gas temperature (EGT) sensors are disconnected or electronically disabled according to the tuning configuration.
- Delete Pipe Installation: The 4” or 5” delete pipe is installed in place of the factory DPF assembly. These pipes are engineered to align with factory hangers and provide proper clearance around the transmission crossmember and drivetrain.
- Sensor & Connection Verification: Any required sensor plugs or fittings are installed, and all clamps are aligned and tightened to ensure a secure, leak-free exhaust connection.
- System Check & Final Verification: After installation, the engine is started and inspected for exhaust leaks. The tuner is used to clear any remaining diagnostic codes, and basic engine operation is verified during a short test drive.
Note: Every EngineGo kit includes a comprehensive, model-specific guide to ensure your installation is seamless and your fitment is guaranteed. For technical deep-dives, step-by-step photos, and specific torque specs, you can find detailed information under the Installation Guide tab on every product page.

FAQ
Does the 6.4 Powerstroke have a DPF or DEF system?
The 6.4L Powerstroke (2008–2010) was the first Ford diesel to feature a Diesel Particulate Filter (DPF) and a Diesel Oxidation Catalyst (DOC), but it does not use DEF (Diesel Exhaust Fluid). Deleting this truck involves removing the DPF/CAT assembly and the EGR system.
Is a tuner required for a 6.4 Powerstroke delete?
Yes, absolutely. Without a "delete-capable" tuner (like an H&S Mini Maxx or EZ Lynk), the truck will immediately enter limp mode or continue trying to perform regeneration cycles. The tuner is required to shut off the sensors and stop the ECM from spraying fuel into the exhaust to clean a filter that is no longer there.
How much will my fuel economy (MPG) improve?
Most 6.4 owners report a gain of 3–5 MPG. The 6.4 is notorious for being a fuel hog because it uses an active regeneration process that dumps raw diesel into the exhaust stroke.() By stopping these cycles and removing the restrictive DPF, efficiency increases significantly.
Will a delete kit fix the 6.4's reliability issues?
It is a major step in the right direction. Deleting the 6.4 eliminates cylinder washing (fuel diluting the oil during regen) and removes the EGR cooler, which is a frequent cause of head gasket failure. While it doesn't fix internal design flaws like piston cracking, it removes the #1 cause of catastrophic emissions-related breakdowns.
What is the difference between a 4" and 5" delete pipe?
- 4" Pipe: Ideal for most trucks. It offers a significant increase in flow and a deep, aggressive tone without excessive "drone" in the cab while towing.
- 5" Pipe: Best for high-horsepower builds (over 600 HP) or owners who want the deepest, loudest exhaust note possible. It offers maximum EGT reduction but can be a tighter fit during installation.
Is it legal to delete my 6.4 Powerstroke?
No. Under federal law (Clean Air Act), removing emissions equipment from a vehicle that was originally equipped with it is illegal for use on public roads. These kits are intended and sold strictly for off-road, competition, or agricultural use only.
