How to service the muffler for different engines on 2008 Ford Mustang?

The manufacturing procedure for the muffler starts by recognizing that the 4.0L model has one muffler while the 4.6L and 5.4L models have two. There is an identical service method for both side mufflers if your vehicle type falls under these models. Place the vehicle on a hoisting system when it remains in NEUTRAL position. You should separate the exhaust coupler from the intermediate pipe and detach it from the catalytic converter assembly so discard the exhaust coupler. Start by opening the muffler clamp then disconnect the muffler from the intermediate pipe before taking out the intermediate pipe from the vehicle. Untuck the muffler away from its position between the muffler isolators before removing it from the location. Application of the isolators requires a torque of 25 Nm (18 lb-ft). Install the new muffler within the isolators and connect it with the intermediate pipe using a fresh exhaust clamp. When attaching the intermediate pipe to the muffler use an exhaust clamp tightened to 48 Nm (35 lb-ft) with the clamp's position limited up to the bottom but not over the notches. Start by placing a new coupler on the intermediate pipe and then align it with the catalytic converter until the converter button settles into the pipe notch. Push the muffler forward to complete the pipe installation in the coupler while verifying the correct placement of the intermediate pipe that ends at the knurled section. The driver should tighten exhaust coupler nuts to 48 Nm (35 lb-ft) and perform alternating tightness at 10 Nm (89 lb-in) intervals.
