Stainless Works FT18HCAT, FT18HCATY, FT21HCATY Installation guide

  • Hello! I've reviewed the provided installation instructions for the Stainless Works Header system for the F-150 5.0L. This document details the entire installation process, from disassembly to final checks, including important steps like RTV sealant usage, sensor handling, and exhaust system connection. I'm ready to answer any questions you might have about this product or the installation process.
  • What sealant is recommended for installing this header?
    Is it necessary to disconnect the battery before starting the installation?
    Can this exhaust system be installed without a lift?
