Overview

The Flo~Pro SS652NB is a 5-inch downpipe-back exhaust system designed for 2011-2019 Ford Powerstroke 6.7L F250/F350 pickup trucks with automatic transmissions. Constructed from 16-gauge aluminized steel or T409 stainless steel, it aims to simplify installation with included clamps, pre-welded contour bends, and improved flanges. This system is intended to provide a noticeable boost in performance, lower EGTs, and amplify airflow.

Show original supplier description

The Flo-Pro SS652NB is a 4-inch diameter, muffler-delete exhaust system engineered from stainless steel. Designed for race applications, this system is compatible with 2011-2019 Ford 6.7L Powerstroke F250 and F350 trucks equipped with automatic transmissions only. It requires models to have a center-mounted rear fuel tank. This exhaust system is designed as a direct fit for factory vehicles without aftermarket suspension or in-bed/gooseneck hitch modifications. However, modifications may be necessary on 2017+ models with the optional hitch prep package. Additionally, the spare tire must be removed for successful installation. This system does not fit Regular Cab trucks; it is compatible with all other cab and bed configurations. It is specifically for models with automatic transmissions and a center-mounted rear fuel tank.
