FAQ
Will this down pipe work with my factory emissions system?
Yes. It is designed to retain the stock emissions equipment and connect at the factory locations.
What trucks does the FAL459 fit?
It fits 2011–2014 F-250/F-350/F-450 6.7L, plus 2015 Cab & Chassis applications. See stainless and EO-listed alternatives above if needed.
Aluminized vs. stainless—what should I choose?
Aluminized steel offers strong value for daily drivers. T409 stainless (see FS9CA459 or FS9459) provides greater corrosion resistance if you drive in harsh winters or salty environments.
