6.7L Powerstroke DPF & DEF Delete Pipe | With Muffler | Ford Cab & Chassis | 2020–2022

Upgrade the exhaust on your 2020–2022 Ford F-450, F-550, or F-600 Cab & Chassis 6.7L Powerstroke with this 4" exhaust section featuring an integrated muffler. Designed specifically for Ford's commercial truck platform, it connects to the existing rear tailpipe using the factory flange.

This configuration allows you to retain the original rear tailpipe rather than replacing the entire exhaust system. It's built for the listed Cab & Chassis applications and is not compatible with standard pickup models.

Overview

Ford's commercial Cab & Chassis trucks use a different exhaust layout than standard Super Duty pickups. This 4" exhaust section is configured specifically for the 2020–2022 F-450, F-550, and F-600 equipped with the 6.7L Powerstroke diesel engine.

The system features 4" diameter piping with an integrated muffler and reconnects to the original rear tailpipe at the factory flange. This makes it a practical option for compatible commercial chassis configurations where the existing rear tailpipe will be retained.

Important: This is not a complete turbo-back exhaust system. It is a replacement exhaust section designed to connect to the original rear tailpipe.
