Preparing for the task
Begin the job by raising the car using a lift, floor jack or ramps. As a precaution, you should never work under a car that is supported only by a jack.
Locating the muffler
Find the muffler-it is connected to the body of the vehicle with rubber muffler hangers bolted on the car's exhaust system.
Lubricating the muffler bolts
If the muffler bolts are already rusted, it may be hard to loosen and remove them. You can fix this by spraying the bolts with penetrating fluid or lubricant. Tap on the flanges of bolts with a hammer or wrench to allow the fluid to seep into the corrosion and do its job. If the rust is severe, you can let the fluid sit for 24 hours to let the lubricant thoroughly soak in.
Removing the old muffler
To remove the old muffler, you need to pull it free from the hangers using your hands. A floor jack will help lessen the tension on the muffler, allowing you to do so. Unbolt the muffler and remove, ensuring that it's balanced to avoid dropping it. When you lower the muffler, the gaskets that secure the exhaust sections should come loose. Otherwise, tap with a hammer or wrench to dislodge.
Preparing for re-installation
Before installing a new muffler, you should clean the mating surfaces using an automotive cleaner and a clean rag. You should also add a slack in the muffler hanger brackets by unscrewing the bolts that hold them in place.
Installing the new muffler
To install a new muffler, begin by balancing it on a floor jack. Lift the muffler until it can be easily fastened onto the front part of the exhaust system. Once it is in place, screw in the new nuts and bolts provided. It is not advisable to use the old hardware with the new muffler. Also, don't forget to reattach the replacement gaskets between the exhaust sections before securing everything. Raise the new muffler to as high as you can without crushing it against the underside of your car. Slowly slide the new hangers on top of the mounting brackets. Start lowering the floor jack until the muffler is at the right height. Tighten the bolts to firmly mount the new muffler to the body. You can now take out the floor jack.
Testing and examining for leaks
To check for leaks, start the vehicle and inspect the attachment point for leaks by feeling around it for any sign of air rushing out. If you find a leak, check the tension on the bolts. If they are tightly attached, the problem may be in the gaskets. In this case you may have to remove the exhaust and reinstall again. If everything works fine, shut off the car and lower it.
