6.7 Powerstroke DPF-Back Exhaust Installation Guide
Off-road / competition use only where emissions rules apply. Emissions-related deletes and DPF-off configurations are not for vehicles operated on public roads or highways subject to those regulations. Confirm local laws before purchase or install. Not legal advice.
This page is Polar Diesel’s HTML overview for installing 2011–2026 Ford 6.7L Powerstroke Polar DPF-back exhaust. DPF-back is not the same as a full delete exhaust—use the full exhaust install guide when that is your kit. Confirm pipe size and finish on the product page, then follow the official DPF-back PDF.
