FAQ
Is this down pipe 50-state legal?
Yes. This product carries CARB EO D-763-1 when used as designed with factory emissions equipment. Always verify local regulations.
What trucks does FS9CA459 fit?
It fits 2011–2014 Ford F-250/F-350/F-450 with the 6.7L Power Stroke, plus 2015 Cab & Chassis applications. For 2015–2016 non–Cab & Chassis, use the stainless FS9460.
What’s the difference between T409 stainless and aluminized steel?
T409 stainless (this part) offers improved corrosion resistance over aluminized steel, making it a better choice for harsh climates. Aluminized saves cost while still improving flow; see FALCA459.
Will this affect my DPF, EGR, or SCR systems?
No. It is designed to retain factory emissions hardware and improve flow pre-DPF.
