Its 304 stainless steel construction and separable sections suit compatible off-road exhaust builds while making positioning easier in the restricted engine-bay area.

Important: This is a catless component intended for off-road or competition applications. Altering emissions-related equipment may cause diagnostic trouble codes and may be prohibited on public roads. Confirm local, state and federal requirements before ordering or installing.

Who This Downpipe Exhaust Is For

• Owners of a verified 2015–2019 F-250, F-350, F-450 or F-550 with the 6.7L turbo-diesel engine.
• Off-road or competition builds requiring a 4-inch catless configuration.
• Installers who prefer two separable sections for easier positioning.
• Trucks using compatible factory-location turbo and downstream exhaust connections.

Product Specifications

6.7L Diesel Downpipe Features

• 4-inch exhaust path: Provides a larger flow path without relying on unsupported horsepower claims.
• Two-piece layout: Allows the front and rear sections to be positioned separately during installation.
• 304 stainless steel: Offers corrosion resistance under exhaust heat, moisture and road exposure.
• Factory-location design: Intended to connect at compatible original turbo and exhaust interfaces.
• Sensor provision: Includes welded bung provision for the applicable sensor arrangement.

Package List

• Two-piece pipe assembly
• Gasket or gaskets supplied with the kit
• V-band clamp or clamps supplied with the kit
• Applicable mounting hardware

A tuner, complete downstream exhaust, additional emissions-delete components and installation tools are not listed as included. Compare the delivered parts with the product images and packing contents before removing the factory pipe.

2015–2019 Super Duty Downpipe: Check Before Ordering

• Confirm the model year: This SKU covers 2015 through 2019. It is not listed for 2011–2014 or 2020-and-newer trucks.
• Confirm the vehicle: Fitment is limited to the listed Ford Super Duty models with the 6.7L diesel engine.
• Confirm the configuration: The pipe is catless and may affect exhaust odor, emissions-system operation and diagnostic behavior.
• Inspect existing modifications: Verify the turbo-side and downstream connections if the truck already has an aftermarket turbo or exhaust.
• Do not assume a universal no-cut installation: Cutting or welding requirements are not confirmed for every modified setup. Compare the connections before disassembly.
• Plan the calibration: A tuner is not listed as included. Discuss CEL, DTC and calibration requirements with a qualified diesel professional.

Fitment

Ford Super Duty Turbo-to-Exhaust System Position

This component carries exhaust gas from the turbo outlet toward the remaining exhaust system. It replaces the front section and is not a complete turbo-back or straight-pipe system.

The 4-inch measurement applies to this assembly, not every component behind it. Adapters or additional work may be necessary if the truck no longer uses factory-location connections.

Installation and Leak Checks

• Allow the engine and exhaust to cool completely, then support the truck with appropriately rated equipment.
• Confirm the year, model, engine and existing exhaust layout before removing factory components.
• Apply penetrating oil to sensor and flange connections before removal.
• Use an appropriate slotted O2 sensor socket and avoid twisting or stretching the wiring.
• Use fresh sealing components and inspect all flange faces before assembly.
• Leave the two sections loose enough for alignment before final tightening.
• Check clearance around wiring, heat shields, brackets, the firewall, steering components and driveline.
• Use reliable vehicle service information for torque requirements because product-specific values are not published with the listing.
• After installation, inspect every joint for leaks and scan the truck for diagnostic trouble codes.

Professional installation is recommended if you do not have the lifting equipment, sensor tools or experience needed to work around the turbo and exhaust system safely.

Catless Downpipe CEL, Calibration and Compliance

Installation may trigger a check-engine light or emissions-related diagnostic trouble codes on a stock calibration. Do not assume code-free operation. Calibration decisions should be handled by a qualified professional for a lawful off-road or closed-course application.

No specific horsepower, torque, fuel-economy or exhaust-temperature gain is guaranteed. Results depend on the truck’s calibration, turbo, downstream exhaust, operating conditions and overall condition. Modifying emissions equipment may violate applicable laws, affect inspection eligibility and influence vehicle warranty coverage.

2015–2019 Ford 6.7L Downpipe FAQs

Q: Which trucks fit this 6.7 Powerstroke downpipe?

A: It is listed for 2015–2019 Ford F-250, F-350, F-450 and F-550 Super Duty trucks equipped with the 6.7L Powerstroke turbo-diesel.

Q: Will this work as a 2015 6.7 Powerstroke downpipe?

A: Yes. The verified 2015 fitment includes the F-250, F-350, F-450 and F-550 Super Duty with the correct engine.

Q: Can I use it as a 2019 F250 downpipe?

A: Yes, provided the truck has the 6.7L Powerstroke and compatible factory-location turbo and downstream connections.

Q: Is this also a 2019 6.7 Powerstroke downpipe for the F-350, F-450 and F-550?

A: Yes. All four listed Super Duty models are included for the 2019 model year.

Q: Does it fit 2020 or newer Super Duty trucks?

A: No. This SKU is listed only for 2015–2019 trucks. Use a separately verified product for later models.

Q: Is the pipe diameter actually 4 inches?

A: Yes. The listed diameter is 4 inches, and the assembly uses a two-piece configuration.

Q: What material is used?

A: The assembly is specified as 304 stainless steel for corrosion resistance under heat and road exposure.

Q: Is this configuration catted or catless?

A: It is listed as catless and intended for off-road or competition applications. Check applicable laws before installation.

Q: Why is the assembly divided into two sections?

A: The sections can be positioned separately, which helps with alignment in the restricted Super Duty engine bay.

Q: Can the original exhaust sensors be retained?

A: The product includes O2 sensor bung provision. Confirm the number, thread and location required by your truck before installation.

Q: What is supplied in the package?

A: The listing identifies the two pipe sections, gasket or gaskets, V-band clamp or clamps and applicable mounting hardware.

Q: Does installation require cutting or welding?

A: A universal no-cut or no-weld installation is not confirmed. Modified systems may require adapters or fabrication, so inspect and measure before disassembly.

Q: Can this component cause a check-engine light?

A: Yes. Changing a catalyst or emissions-related exhaust configuration may produce CELs or diagnostic trouble codes on a stock calibration.

Q: Is a tuner included?

A: No tuner is listed as included. Discuss calibration requirements and legal restrictions with a qualified professional.

Q: How much horsepower will it add?

A: No fixed gain is claimed because no product-specific dyno protocol is supplied. Results vary with the turbo, calibration, downstream exhaust and vehicle condition.

Q: Is this the same as a complete straight-pipe system?

A: No. It replaces the front exhaust section. A complete straight-pipe or turbo-back setup contains additional downstream components.

Q: What should be checked after installation?

A: Inspect every joint for leaks, confirm clearance from wiring and nearby components, verify sensor connections, listen for contact or vibration and scan for diagnostic trouble codes.
