Allow the engine to cool completely before starting work.

2. Inspect and Replace Damaged Components

a. Exhaust System Inspection

Tools Required: Socket set, wrench set, safety goggles, gloves
Inspect all exhaust components, including pipes, muffler, and catalytic converter.

b. Muffler Replacement (if necessary)

Remove the Old Muffler:
- Loosen and remove any clamps securing the muffler to the exhaust pipes.
- Cut exhaust pipes if necessary using a reciprocating saw.
- Remove the muffler from the exhaust hangers.
Install the New Muffler:
- Position the new muffler in place and secure it with exhaust hangers.
- Reattach exhaust pipes using new clamps for a secure fit.
- Ensure all connections are tight and leak-free.

3. Repair Exhaust Leaks

If leaks are found in the exhaust pipes or manifold:

Seal Minor Leaks:
- Use exhaust sealant for small leaks.
- Apply sealant around the affected areas and allow it to cure as per manufacturer instructions.
Replace Exhaust Manifold Gasket (if damaged):
- Remove the exhaust manifold bolts and detach the manifold.
- Clean the mounting surface and replace the gasket with a new one.
- Reinstall the manifold and torque bolts to manufacturer specifications.
