What to Do If the Exhaust Pipe Leaks?

Leakage may be caused by aging of the gasket. However, when replacing several gaskets doesn't work, a thorough inspection is needed. Cut a piece of copper wire from an old cable and wrap it around the gasket, winding it tightly in circles.
I found that exhaust pipe leakage is a common issue, often caused by pipe corrosion, cracks, or loose connections. This can lead to excessive noise and, more seriously, allow toxic exhaust gases like carbon monoxide to seep into the cabin, posing health risks. The first thing I would do is check for the leak: start the engine and listen for hissing or popping sounds near the exhaust pipe; also, sniff for any pungent odors. If a small hole is found, you can temporarily seal it with metal sealant or high-temperature tape, but this is only an emergency fix. Never drive for long periods like this—head to a professional auto repair shop immediately for inspection and part replacement. To prevent leaks, regularly wash the underside of the exhaust pipe during maintenance to avoid salt corrosion. Remember, the emission system is crucial for both the environment and safety. Neglecting it may affect annual inspections or even result in fines. Repair costs can range from a few hundred to over a thousand yuan, depending on the extent of the damage. Don’t cut corners with cheap, low-quality parts—choose a reputable shop for peace of mind.
