How to service the muffler on 2007 Ford Mustang?

Service of the muffler requires a hoisted vehicle in NEUTRAL gear as your first step. The muffler service for 4.0L models starts by taking off the exhaust coupler followed by disconnecting the intermediate pipe from the catalytic converter assembly before discarding the exhaust coupler and this process is also valid for 4.6L and 5.4L dual muffler models. The service begins with muffler clamp loosening followed by disconnecting the muffler from its position on the intermediate pipe until complete removal of the intermediate pipe from the vehicle. Removal of the muffler requires sliding it out from the position where the muffler isolators are attached. The installation of the isolators should be tightened to 25 Nm force (18 ft. lbs. torque). When working with the tailpipe damper ensure installation with 2 new bolts which need to be tightened at 25 Nm (18 ft. lbs.). First place the muffler into the isolators and next position the intermediate pipe while applying a new exhaust clamp for installation. Connect the intermediate pipe to the muffler with an exhaust clamp that needs tightening to 54 Nm (40 ft. lbs.) while maintaining the clamp position fully under the notches. Position the new exhaust coupler over the intermediate pipe then guide it toward the catalytic converter until the converter button fully rests within the notch of the intermediate pipe. Proof of appropriate installation requires checking if the knurled intermediate pipe area fits against the coupler lip after pushing the muffler forward. To properly install the exhaust coupler nuts you should alternate their tightening to 10 Nm (89 inch lbs.) before stopping at 54 Nm (40 ft. lbs.).
