FAQ
Will this fit my 2008–2010 6.4L without other mods?Yes. It’s a direct replacement 4" down pipe for factory 6.4L Super Duty configurations.
Is FAL455 legal for use in California?
No. Choose the 50-state legal alternatives: FALCA455 (aluminized) or FS9CA455 (stainless).
Aluminized vs. Stainless — which should I choose?
Armor Lite (aluminized) offers great value in mild climates. T409 stainless (Armor Plus) like FS9CA455 or the 2-piece FS9455 is better for road salt/coastal exposure.
Which exhaust system pairs best with this down pipe?
For a simple, value-focused MBRP setup, match it with the S6282AL 4" filter-back.
