Zero Backpressure - With no internal restriction, exhaust gases flow freely from the turbo all the way through the system. The turbo spools faster, and throttle response feels exceptionally immediate.
30–40 lbs of Weight Reduction - Removing the heavy ceramic filter assembly reduces chassis weight and frees up additional space for future inspection and maintenance.
EGT Reduction of 200–300°F - Heat is no longer trapped inside the factory aftertreatment system. Instead, it exits quickly, reducing the need to constantly monitor EGT during towing and uphill driving.
Eliminates Regeneration and Prevents Oil Dilution - No additional diesel is injected for active regeneration. Fuel economy may improve by 2–5 MPG, oil life is extended, and engine bearings receive greater long-term protection.
Unleashes the Original Turbo Whistle - The hollow straight-through pipe acts like an amplifier, fully releasing the distinctive, sharp whistle of the 6.7L Power Stroke under hard acceleration.

This 6.7 Powerstroke DPF & CAT Delete Race Pipe is a completely hollow 4-inch stainless steel pipe with no internal filter media. It directly replaces the heavy factory DPF and catalytic converter assembly.
| Comparison | Factory DPF + Cat Assembly | SuncentAuto Race Pipe |
|---|---|---|
| Internal Structure | Honeycomb ceramic filter media | Completely hollow |
| Exhaust Restriction | High | Free-flowing straight pipe |
| Exhaust Backpressure | Baseline | Eliminated |
| EGT During Towing and Climbing | Rises significantly | 200–300°F lower |
| Weight | 50–60 lbs | 30–40 lbs lighter |
Result: Exhaust gases flow freely from the turbo without obstruction. Resistance against the turbine is greatly reduced, allowing the turbo to build boost faster and providing exceptionally responsive throttle feel.
The hollow straight-through pipe acts like an amplifier, producing a deep, raw, and aggressive diesel exhaust tone. Under hard acceleration, the distinctive high-pitched turbo whistle becomes much more pronounced and instantly recognizable.
A 4-inch pipe is considered the ideal torque-oriented diameter for the 6.7L Power Stroke. Within the engine's low- and mid-range torque band, the 4-inch tubing helps maintain strong exhaust pulse velocity and scavenging effect. This helps preserve low-end torque and provides stronger response during initial acceleration, towing, and load carrying.
When considering a 2017 F250 delete pipe or 2019 F250 delete pipe, a 4-inch pipe is our recommended choice.
Direct Bolt-On Fitment: The pipe bends follow the factory routing and align with the original hanger locations without requiring excessive bending or modification.
Seamless Connection: The front connects to the downpipe, while the rear connects to the factory rear exhaust section. Clamps secure and seal the joints to help prevent exhaust leaks and unwanted whistling noises.
The EGR system recirculates a portion of the exhaust gases back into the intake to lower combustion temperatures and reduce NOx emissions.
However, soot-rich exhaust gases continually enter the intake system, contributing to carbon buildup inside the intake manifold and EGR valve. Common problems may include a sticking EGR valve and an EGR cooler that cracks after repeated heating and cooling cycles, with repair costs potentially exceeding $2,000. Recirculated exhaust also displaces fresh intake air, reducing combustion efficiency.
Removing the EGR system at the same time can deliver several additional benefits:
🌬️ Cleaner Intake Air - The cylinders receive fresh air without recirculated exhaust contamination, potentially improving turbo response by 15–20%.
⚡️ Additional Power Potential - More oxygen combined with professional tuning may release an additional 30–50 HP.
🛡️ Improved Reliability - Eliminates concerns related to carbon buildup, sticking EGR valves, and cracked EGR coolers.
⛽ Additional Fuel-Economy Improvement of 2–5 MPG - Improved combustion efficiency may further enhance fuel economy.
An EGR delete complements a DPF delete. Together, they complete the transformation of the 6.7L Power Stroke from a restricted factory configuration into a fully optimized performance setup.
Removing the EGR system is not required, but it may be considered by owners seeking maximum performance and a more comprehensive long-term reliability solution.
Without ECU calibration to disable the factory aftertreatment monitoring functions, including DPF and EGR-related fault codes, the check engine light may illuminate immediately and the vehicle may enter limp mode with reduced speed and torque. Check our tuner here: Diesel Delete Tuner.
