Unleash the full potential of your 2020-2022 Ford 6.7L Powerstroke with our 4" Downpipe-Back DPF Delete Exhaust System. Engineered to boost horsepower and torque, this high-performance setup delivers a commanding, aggressive exhaust tone while maximizing reliability and durability.
Built for owners who want more from their truck, this 6.7 Powerstroke DPF delete kit is designed for 2020-2022 Ford F-250 Super Duty, F-350 Super Duty, and F-450 Super Duty. This 4" Downpipe-Back exhaust system with muffler replaces the restrictive factory DPF and CAT section with a freer-flowing path that improves exhaust efficiency, reduces back pressure, and delivers a deeper, more refined diesel sound.
The 2020-2022 6.7L PowerStroke's factory exhaust system was originally designed to meet emissions regulations. However, over time, these restrictive components have developed some issues. They can obstruct airflow, increase back pressure, and raise exhaust temperatures under load.
The DPF delete and upgrade kit truly changes this. By removing the limiting DPF and catalytic converter sections, exhaust gases can be expelled from the engine more quickly, bringing the truck's response closer to that of a heavy-duty diesel engine.
| Performance Aspect | Factory Exhaust Setup | Vigor Diesel 4" Downpipe-Back System |
|---|---|---|
| Exhaust Flow Efficiency | Limited by factory DPF and catalytic converter | Larger 4" piping improves exhaust evacuation |
| Back Pressure | Higher pressure under load and towing | Lower restriction for smoother airflow |
| Power Output | Restricted by stock emissions components | +24 hp / +38 lb-ft potential gains |
| Performance With Tuning | Limited tuning headroom | Supports builds up to +150 hp |
| Heat Control | Heat retained within emissions system | Exhaust temps reduced by up to 220°F |
| Fuel Efficiency | Extra fuel used during regen cycles | Possible 4–6% fuel efficiency improvement |
| Service Costs | DPF service, DEF fluid, replacement costs | Removes most emissions-related maintenance |
| Exhaust Tone | Quiet and heavily muffled | Deeper diesel tone with clearer turbo whistle |
This system is designed for:
Fits 6.7L Powerstroke diesel models only.
Will not fit regular cab models. Will not fit Cab & Chassis models.
When upgrading to a downpipe-back DPF delete kit, truck owners typically choose between a system muffler-equipped system and a muffler-delete (straight pipe) system. Here's a comparison.
| Feature | Downpipe-Back With Muffler | Downpipe-Back Without Muffler |
|---|---|---|
| Exhaust Sound | Deep, controlled diesel tone | Loud, aggressive straight-pipe sound |
| Cabin Noise | More comfortable for daily driving | Noticeably louder inside the cab |
| Exhaust Flow | High-flow performance design | Maximum unrestricted airflow |
| Turbo Whistle | Clear and noticeable | Sharper and louder turbo whistle |
| Driving Experience | Balanced performance and comfort | Performance-focused, race-style sound |
| Best For | Daily driving, towing, long trips | Competition use, aggressive builds |
This Vigor Diesel 6.7 Powerstroke DPF delete exhaust system is made from T-409 stainless steel with a 2mm wall thickness. Compared with many OEM systems, T409 provides better heat tolerance and long-term durability in harsh diesel exhaust conditions.
The benefit of a Downpipe-Back exhaust is not just the larger diameter. It is how the system manages flow. This design uses smoother routing and low-restriction piping to improve exhaust evacuation and reduce pressure where it matters most.
Every Vigor Diesel exhaust upgrade is backed by support designed for real truck owners:
This 6.7 Powerstroke DPF delete exhaust system offers a strong balance of material quality, fitment, performance value, and long-term savings.
This 4-inch exhaust-to-tail section system can be installed directly in the location of the original exhaust pipe, replacing the remaining tail section of the exhaust system. The system features a vehicle-specific piping design, perfectly compatible with the 2020-2022 Ford 6.7L Powerstroke Super Duty platform.
Basic installation typically includes:
Most installations can be completed using standard hand tools and a vehicle lift or jack stand. For best results, installation by a professional is recommended.
Because this system removes the original emissions components, ECU tuning is required after installation. If not properly tuned, the vehicle's computer will detect the absence of a DPF and catalytic converter, potentially triggering the following malfunctions:
Proper tuning also helps unlock the potential performance gains from DPF removal from the exhaust system, including improved throttle response and increased horsepower.
We provide a detailed installation guide to help you complete the installation. Please refer to the Ford 6.7-liter PowerStroke Downpipe-Back Exhaust Installation Blog for step-by-step instructions.
