6.7 Powerstroke Polar Exhaust Installation Guide
Off-road / competition use only where emissions rules apply. Full delete / DPF-off style exhaust configurations are not for public roads where prohibited. Confirm local laws and required tuning before install. Not legal advice.
This page is Polar Diesel’s HTML overview for installing 2011–2026 Ford 6.7L Powerstroke Polar exhaust systems (4" and 5", muffler and polished options as applicable). Confirm pipe size, material, and year fitment on the product page, then follow the official full-exhaust PDF for the hardware sequence. For DPF-back-only systems, use the separate DPF-back PDF on the instructions hub—do not mix the two manuals.
