Greatly reduces exhaust backpressure and helps unlock real engine potential with proper tuning.
The 5-inch free-flow design improves exhaust flow for quicker and stronger acceleration.
More heat-resistant and corrosion-resistant than factory aluminized steel for long-term durability.
No cleaning, no regeneration fuel use, and no DPF clogging risk—saving more in fuel and repairs.
The straight-through design delivers a deeper, stronger, and more powerful diesel exhaust note.

This 5" downpipe-back DPF delete exhaust system fits 2011–2022 Ford F-250 and F-350 trucks with the 6.7L Powerstroke diesel engine. It improves exhaust flow, lowers backpressure, supports better turbo response, and delivers a deeper diesel sound with proper ECU tuning.
Removing the DPF system may reduce costs from regeneration, cleaning, replacement, extra fuel use, sensors, and related components.
Actual savings vary by mileage, load, tuning, installation, and vehicle use.
With proper tuning, this 5" exhaust can improve flow, reduce restriction, and help increase horsepower and torque by 5%–10%.
More exhaust capacity than the factory baseline.
Less restriction for smoother exhaust flow.
More horsepower and torque with proper tuning.
Results vary by truck condition, tuning, installation, and supporting modifications.
T-409 stainless steel is built for higher heat, moisture, road salt, and longer service life.
| Feature | T-409 Stainless Steel | Aluminized Steel |
|---|---|---|
| Corrosion Protection | Chromium inside the material | Aluminum coating on carbon steel |
| Heat Resistance | 750–800°C | Around 600°C |
| Service Life | About 10+ years | About 3–5 years |
| Best Use Case | All conditions, especially snow and road salt areas | Short-term use in dry, salt-free areas |
Bottom line: The lower upfront cost of aluminized steel may return as repairs or rework later.
Choose 4" downpipe-back exhaust for a balanced upgrade. Choose 5" for stronger flow, lower backpressure potential, deeper sound, and a more aggressive large-diameter look.
A DPF + EGR delete combo helps cut off carbon buildup at the source. Even after DPF removal, the EGR system can still send exhaust gas back into the engine. Removing both systems helps bring in more fresh air for better throttle response, stronger mid-to-high RPM acceleration, and improved fuel efficiency.
Shop Recommended All-in-One KitRecommended process: tune first, then install the hardware.
Without tuning, the ECU may trigger warning lights, fault codes, or limp mode. Proper tuning tells the ECU that the hardware has been removed and helps release the real power potential.
