Muffler Installation and Repair Tips for 2003 Mercury Grand Marquis

  • Q: What are the steps involved in removing and installing the production muffler and tailpipe assembly on 2003 Mercury Grand Marquis?
    A: The tail pipe assembly and production muffler are one assembly whereas the service assembly consists of two. Switch off the air suspension system before removal, to prevent unexpected inflation. Lift up the car, take off the clamp, and cut apart the muffler and tail pipe with an exhaust cutter. Installation is to be reversed.
