The exhaust system consists of the exhaust manifolds, catalytic converters, muffler, resonators, the tailpipe and all connecting pipes, brackets, hangers and clamps. The exhaust system is attached to the body with mounting brackets and rubber hangers. If any of the parts are improperly installed, excessive noise and vibration will be transmitted to the body. Regular inspections of the exhaust system are necessary to keep it safe and quiet. Look for any damaged or bent parts, open seams, holes, loose connections, excessive corrosion or other defects which could allow exhaust fumes to enter the vehicle. Inspect the exhaust system connections for leakage and the exhaust system rubber hangers for damage. Also check the catalytic converter when you inspect the exhaust system. Deteriorated exhaust system components should not be repaired; they should be replaced with new parts. If the exhaust system components are extremely corroded or rusted together, welding equipment will probably be required to remove them. The convenient way to accomplish this is to have a muffler repair shop remove the corroded sections with a cutting torch. If, however, you want to save money by doing it yourself, simply cut off the old components with a hacksaw. If you have compressed air, special pneumatic cutting chisels can also be used. If you do decide to tackle the job at home, be sure to wear safety goggles to protect your eyes from metal chips and work gloves to protect your hands. When repairing the exhaust system, work from the back to the front when removing exhaust system components. Apply penetrating oil to the exhaust system component fasteners to make them easier to remove. Use new gaskets, hangers and clamps when installing exhaust systems components. Apply anti-seize compound to the threads of all exhaust system fasteners during reassembly. Be sure to allow sufficient clearance between newly installed parts and all points on the underbody to avoid overheating the floor pan and possibly damaging the interior carpet and insulation. Pay particularly close attention to the catalytic converter and heat shield. Periodically inspect the heat shield for cracks, dents and loose or missing fasteners. Inspect the converter for cracks or other damage. If the catalytic converter requires replacement, it should be done promptly.

A properly installed exhaust system is crucial to prevent excessive noise and vibrations from being transmitted to the vehicle's body.

It's important to inspect the heat shield for cracks, dents, loose or missing fasteners, and the catalytic converter for cracks or damage. Replacing a damaged catalytic converter should be done promptly.

Regular inspections of the exhaust system are necessary to ensure safety and minimize noise. You should look for damaged or bent parts, open seams, holes, loose connections, excessive corrosion, or other defects that could allow exhaust fumes to enter the vehicle.
