REMOVAL & INSTALLATION



  1. Support the vehicle securely. Apply penetrating oil to all clamp bolts and nuts you will be working on. Support the vehicle by the body, if possible, to increase working clearances.
  2.  
  3. If the tailpipe is integral with the muffler, and the muffler must be replaced, cut the tail pipe with a hacksaw right near the front of the muffler. The replacement muffler is then installed using a clamp to attach to the tailpipe.

  1. Clean the mating surfaces of pipes or the muffler to ensure a tight seal. Use new insulators, clamps, and supports unless the condition of old parts is very good. Note that the slip joint at the front of the muffler uses a U-clamp. The bolts should be tightened to 270 inch lbs. (30 Nm) on cars with normally aspirated engines and to 360 inch lbs. (40 Nm) on turbocharged cars.
