The MagnaFlow is a beautiful system.

The hardest part of the install is getting your old system off. Use a reciprocating saw to cut your old pipe off just in front of the rear wheels in front of the bend. Cut the pipe 3.5" after the 2nd Cat (at the #6), or Isolator as Ford Calls it. Use a pipe cutter for a cleaner cut.

Use anti-seize on all the nuts and tighten down from front to back. And you're done.
