The exhaust system includes the exhaust manifolds, catalytic converter, muffler, tailpipe, and all connecting pipes, flanges, and clamps, and is isolated from the vehicle body and chassis components by rubber hangers that should be periodically inspected for cracks or deterioration, replacing them as necessary. Regular inspections are essential to maintain safety and quiet operation, checking for damaged or bent parts, open seams, holes, loose connections, excessive corrosion, or other defects that could allow exhaust fumes to enter the vehicle; any deteriorated components should be replaced rather than repaired. For extremely corroded or rusted components, a cutting torch is the most convenient removal tool, but if unavailable, a hacksaw or special pneumatic cutting chisels can be used, with safety goggles and work gloves recommended for protection. When repairing the exhaust system, work from the back to the front, apply penetrating oil to fasteners for easier removal, use new gaskets, hangers, and clamps, apply anti-seize compound to fastener threads during reassembly, and ensure sufficient clearance between newly installed parts and the underbody to prevent overheating and potential damage to the interior.
