The 2003-07 Ford 6.0L Powerstrokes came factory equipped with a 3.5" turbo back aluminized exhaust with a catalytic converter and muffler. While this system is reasonably adequate for stock to mildly powered trucks, a larger diameter system or higher flow system from Diamond Eye, Magnaflow, MBRP, or Silverline is mandatory on any Powerstroke equipped with even mild upgrades, or for those towing heavy loads.
