Description

Flo-Pro Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.
The 421011 & 422011 is a 4" downpipe for the 2008-2010 Ford F-Series by Flo-Pro. It replaces your restrictive OE downpipe with 4" high-flow piping that bolts directly to your existing turbo and exhaust system with basic hand-tools.
Part Number: 421011 & 422011

Features

  • 4" Downpipe
  • Increased Power
  • Increased Fuel Mileage
  • Aluminized & Stainless Steel Options
  • Fits OEM Turbo & Exhaust

Stainless vs Aluminized

Aluminized steel is the budget-friendly choice. It has a protective coating that holds up well, but once that coating wears it will eventually rust through, especially in salted winter climates. The stainless option is T409 stainless, an automotive-grade steel built to resist rot, and it will typically outlast the truck. T409 is not polished show-grade stainless, so light surface rust or discoloration can still show up over time. That is cosmetic only and won't affect performance or service life.

Notes

  • This will Only fit Ford F-Series Powerstrokes with an Automatic Transmission
