How to service the muffler for different engine types on 2009 Ford Mustang?

Service of the muffler requires two steps: understanding that the 4.0L has a single muffler yet the 4.6L and 5.4L engines use dual mufflers for both sides if present. Place the vehicle in NEUTRAL position then mount it on a hoist. Access the exhaust coupler first before removing the intermediate pipe connected to the catalytic converter assembly and properly dispose of the exhaust coupler. Start by unclasping the muffler and detaching it from the intermediate pipe before taking off the intermediate pipe from the vehicle. Remove the muffler through by operating it from the muffler isolation system. The isolator bolts require tightening to 25 Nm before installing the new muffler by sliding it into position. Install the intermediate pipe by using a new exhaust clamp which needs to be tightened to 48 Nm (35 lb-ft) while allowing the clamp to sit at the bottom of the notches. Use the intermediate pipe to position a fresh exhaust coupler against it before positioning it properly on the catalytic converter. Check that the converter button fits adequately into the intermediate pipe notch. Fully enter the pipe into the coupler by pushing the muffler forward to check that the intermediate pipe properly fits into its position with the knurled section situated at the coupler lip. The final assembly requires tight installation of exhaust coupler nuts to 48 Nm using 10 Nm steps (35 lb-ft and 89 lb-in).
