Match the turbo-back exhaust to your 6.0L pickup
This exhaust listing is for the stated 2003–2007 Ford Super Duty pickup applications with the 6.0L Powerstroke and an automatic transmission. It supplies a turbo-back arrangement for a competition build, including replacement of the factory catalytic-converter section. Cab & Chassis fitment is excluded.
Available diameter and material combinations
| Selection | Stainless-steel grade |
|---|---|
| 4-inch turbo-back | T409 |
| 5-inch turbo-back | T409 |
| 5-inch turbo-back | T304 |
Choose one of the actual combinations in the selector. The presence of both steel grades on this page does not mean every diameter is offered in both materials.
Vehicle checks before checkout
- Model year within the listed 2003–2007 range.
- 6.0L Powerstroke engine and automatic transmission.
- Pickup exhaust routing, not Cab & Chassis.
- The stated cab/bed applications include Extra Cab or Crew Cab with short or long boxes; confirm the specific truck configuration.
- Dually applications are listed, subject to the same fitment checks.
Package and layout
The selected package includes the exhaust tubing, stainless downpipe and transition, mounting hangers and required installation hardware. The construction is bung-free. A muffler is not included in the standard assembly.
Plan for installation and sound
Professional installation is recommended. Have the installer check alignment, mounting locations and clearance against the instructions for the selected system. The muffler-free arrangement changes the exhaust sound; a separately purchased muffler with the corresponding 4-inch or 5-inch connections can be considered when planning the setup.
Questions about the options
Is there a 4-inch T304 selection on this listing?
The current choices are 4-inch T409, 5-inch T409 and 5-inch T304. Order from the displayed combinations.
Does the package include a muffler?
No. Muffling is an additional choice rather than part of the supplied race assembly.
Will it fit a manual-transmission or Cab & Chassis truck?
Neither is within the compatibility stated for this listing. Have JS Speed Diesel identify a suitable alternative before ordering.
Use restriction: This emissions-modifying exhaust is intended for off-road or competition applications. Confirm the requirements applicable to the truck before purchase or use.
