Air compressor and tools (not necessary)

Sawzall (if available)

Ratchet

15mm deepwell socket

11/16” socket

STEPS & TOOLS

  1. Break the lugs on the passenger side rear wheel.
  2. Jack the car up and place on stands.  I placed stands under all four corners.

  4. Remove one bolt using an 11/16” socket from the axle damper (Fig. 1).

  1. Cut the stock exhaust using a sawzall with a metal cutting blade (if available) a few inches behind the muffler.  Watch for brake lines or anything else that may get in the way.
  2. Remove four bolts using a 15mm deepwell socket (see Fig. 2).

  1. Remove stock exhaust.
  2. Remove the stock hangers with a 3” extension and a 10mm socket.
  3. Dryfit the Magnapack on the floor so you know what pieces go where (Fig. 3).  Keeping old exhaust to reference may help.

  1. Place the two pieces that go over the axle.
  2. Attach the new hangers supplied by Magnaflow using the stock fasteners.
  3. Attach all pieces of the new exhaust, starting at the H-pipe, do not tighten.
  4. Attach exhaust to the hangers, excluding the tips.
  5. Check all over for clearance.
  6. Tighten the four 15mm bolts at the H-pipe (or any other pipe you may be using).
  7. Tighten eight bolts for the supplied U-bolts using a 15mm socket (Fig. 4)

  1. Drive car for 30 or so miles, jack it up and place the stands, and re-torque all bolts again.

 

SUMMARY

Install took a little over an hour, maybe an hour and a half, including breaks using air tools.  This is the easiest thing I’ve done to date to the Stang, the parts fit great and were of very good quality.  I imagine someone with minimal wrenching skills could handle this project pretty easily in 2-3 hours, and a more experience person in an hour or less.
