Select a 4-inch exhaust by model year and material
This downpipe-back system is the 4-inch exhaust option for the listed 2011–2025 Ford Super Duty pickups with the 6.7L Powerstroke. It replaces the Cat/DPF section as part of the exhaust assembly. Match both the year group and the stainless-steel construction to your truck before checkout.
Ordering choices
| Choice | Available selections |

Confirm pickup fitment first
The stated application covers the listed F-250, F-350 and F-450 pickup configurations. Cab & Chassis vehicles are excluded. If the truck's body configuration is unclear, have JS Speed Diesel check it before you order.
What the system provides
- A stainless exhaust assembly with Cat/DPF replacement piping.
- Hangers positioned for the vehicle's original mounting locations.
- A choice of standard or flanged 304 construction where shown in the selector.
A compatible 4-inch muffler or exhaust tip can be considered separately to suit the build. Confirm any additional parts required for the selected configuration.
Installation planning
Arrange compatible race tuning and review the exhaust instructions before beginning vehicle work. The selected assembly must match the truck's year group and pickup layout. Exhaust changes alone do not establish a particular horsepower, fuel-economy or temperature result.
Questions about this listing
Will this give me a 5-inch system?
No. Every selection on this listing is the 4-inch system. A 5-inch exhaust is a different product.
Why are there two year groups?
The selector separates the earlier 2011–2022 application from 2023–2025. Order against the truck's actual model year rather than choosing solely by pipe material.
Can I use it on a Cab & Chassis truck?
No. That body configuration is outside this product's stated fitment.
Use restriction: This exhaust modifies emissions equipment and is offered for off-road or competition use. Check the requirements that apply to the vehicle before purchase or installation.
