Product Description

The MBRP FAL455 is a 4in aluminized steel turbo downpipe built for 2008-2010 Ford F-250, F-350, and F-450 Super Duty trucks equipped with the 6.4L Powerstroke diesel engine. As part of MBRP's Installer Series, it's designed to deliver noticeably more exhaust flow than the restrictive factory downpipe at an accessible price point.

Constructed from heavy-duty aluminized steel and mandrel-bent for smooth airflow, this downpipe is jig-manufactured for precise, repeatable fitment. The 2-piece design simplifies installation, and improved exhaust flow helps reduce exhaust gas temperatures (EGTs), which can ease strain on the turbo during towing or hard acceleration. Installation hardware is included, so no separate hardware purchase is needed.

Because this downpipe is designed for off-road and emissions-exempt use, it is not for sale or use in California, and removing the OEM catalytic converter it replaces may violate emissions regulations depending on your local laws - buyers should confirm legality in their area before installing. It's a solid entry point for Powerstroke owners looking to add flow without stepping up to a full stainless steel system.
