This 6.7L Powerstroke 5" Downpipe-Back DPF Delete Exhaust System for 2011-2022 Ford F250 and F350 is designed to replace the restrictive factory exhaust system located behind the downpipe. Designed for off-road and racing applications, this system improves exhaust efficiency, supports higher horsepower output, and enhances overall driving response.
Not compatible with Cab & Chassis commercial style trucks.
Factory-installed exhaust systems include components that limit emissions, such as the diesel particulate filter (DPF). While intended to reduce emissions, these components can, over time:
For truck owners who frequently drive in off-road, racing, or professional competition environments, these limitations restrict the engine's full performance. Therefore, many owners choose to remove the DPF system.
| Comparison Item | Stock Exhaust System | Downpipe-Back DPF Delete Exhaust |
|---|---|---|
| System Design | Retains the factory DPF and related aftertreatment components | Replaces the exhaust from the downpipe back with a more free-flowing design |
| Exhaust Restriction | Higher backpressure | Lower backpressure and smoother exhaust flow |
| Sound | Quieter, factory-style tone | Deeper, louder, and more direct exhaust note |
| Driving Feel | More focused on daily comfort and smoothness | More direct throttle response and improved exhaust efficiency |
| Maintenance Focus | May involve DPF regeneration, clogging, and cleaning issues | Can reduce DPF-related maintenance concerns |
| Intended Use | Designed for factory on-road use | Commonly used for off-road or race applications |
Compared to the stock exhaust, this 6.7 Powerstroke 5 inch downpipe back exhaust emphasizes higher flow rate, lower back pressure, and a stronger diesel sound response.
The original DPF system requires regular regeneration, cleaning, and ultimately replacement. These maintenance needs significantly increase costs with high mileage use. By removing the DPF system for off-road or racing applications, owners can reduce:
Total potential net savings up to $26,000 after components & tuner.
Actual results will vary depending on driving habits and load conditions.
Besides reducing costs, removing a restrictive diesel particulate filter (DPF) system can directly improve exhaust efficiency for your 6.7 Powerstroke engine. Installing a 5-inch straight-through DPF removal system can:
With proper ECU tuning, many modifications can increase horsepower by 30–80+ (the exact increase depends on the modifications). Compared to the stock exhaust, owners generally report smoother acceleration and a deeper, more aggressive exhaust note.
This DPF delete downpipe-back exhaust system for the 6.7L Powerstroke diesel engine is made of T-409 stainless steel . 409 stainless steel is widely used in heavy-duty exhaust systems due to its perfect balance of strength, heat resistance, corrosion resistance, and cost-effectiveness.
Compared to aluminized steel, 409 stainless steel generally offers better resistance to corrosion, scaling, and thermal abrasion. While aluminized steel may be less expensive, 409 stainless steel is often the preferred choice for diesel exhaust systems because it achieves a better balance between durability, performance, and value.
| Feature | 409 Stainless Steel | Aluminized Steel |
|---|---|---|
| Durability | Strong and long-lasting | Moderate |
| Heat Resistance | Handles high heat well | Fair |
| Corrosion Resistance | Better rust resistance | Better than plain steel |
| Performance Use | Good for diesel/performance exhaust | Common budget option |
| Service Life | Good long-term value | Shorter in harsh conditions |
| Best For | Off-road, towing, racing | Budget replacement |
| Overall Value | Balanced durability and cost | Lower upfront cost |
| Comparison Item | 4" DPF Delete Exhaust | 5" DPF Delete Exhaust |
|---|---|---|
| Pipe Diameter | Larger than stock and a noticeable upgrade | Larger diameter with stronger exhaust flow potential |
| Flow Characteristics | Balances improved flow with everyday usability | More focused on maximum flow and lower backpressure |
| Sound | Noticeably louder than stock, but more restrained | Deeper, fuller, and more aggressive sound |
| User Preference | Better for those wanting a more balanced upgrade | Better for those prioritizing sound and exhaust flow |
The 4-inch version is more balanced, while the 5-inch version is more aggressive; if you value the power of the sound and the visual effect of a large-diameter speaker, you can choose the 5-inch version.
