How to Remove the Muffler From a Car

Mufflers are in a precarious position. Located under a car, theyre vulnerable to bumps, rocks and road debris that can cause holes or other damage. If you have muffler problems, youll know right away because of the loud noise. Replacement is often the best option to restore your car to quiet operation. Before you can mount a new muffler, youll have to remove your old one. Fortunately, the process is not too difficult

Instructions

1

Prepare the car for muffler removal by jacking it up with a standard car jack or putting it up on car ramps. Since the muffler is located underneath the car, youll have to be able to access that area and move around well enough to do the required work.

2

Put on protective goggles before starting the actual removal work. A muffler can be rusty, and small chips can easily fly up into your eyes. Goggles will protect them from any debris that might fly around while you do the cutting and prying required to remove the muffler. You may also wish to wear work gloves to protect your hands from cuts.

3

Lubricate the muffler clamp nut with a coating of penetration oil, and apply the oil to the fittings as well. These parts tend to be dusty and dirty because of their position underneath the car, which exposes them continually to dirt. The oil will make them easier to manipulate and remove.

4

Remove the nuts that connect the muffler to the exhaust pipes. If the oil does not loosen the nuts well enough to be turned for removal, or if the muffler is welded in place, cut the connecting pipes with your hacksaw. Then, remove muffler nuts from the hanger using your impact wrench. Allow it to drop down so it can be loosened from the rear mounts.

5

Using the pry bar, complete the removal process by removing the muffler from the rubber straps that are keeping it in place. You can now take the car down from the jack or ramps.
