Identify the section of the exhaust system where the leak is located.
If necessary, remove the heat shield using a socket set.
Remove any exhaust clamps or bolts using a socket wrench to access the leaky section.

4. Replace Gaskets or Repair Leaks

If a gasket is damaged, remove the old gasket and clean the mating surfaces.
Install a new exhaust gasket, ensuring it is aligned properly.
For small cracks, apply high-temperature exhaust sealant to seal the leaks, following the manufacturer's instructions.
