Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect the battery to prevent any electrical issues during repair.

2. Remove Damaged Components

Lift the vehicle using a jack and secure it with jack stands.
Remove any heat shields or underbody covers if necessary to access the exhaust system.
Use a socket set to unbolt any components that are damaged or need replacement, such as exhaust pipes, catalytic converters, or mufflers.

3. Inspect and Replace Gaskets/Seals

Remove the old gaskets from the joints where leaks were identified.
Clean the surfaces of the exhaust components where the gaskets will be installed.
Apply exhaust sealant to the new gaskets and place them onto the clean surfaces.
Reattach the exhaust components, ensuring all bolts are tightened to the manufacturer's specifications using a torque wrench.
