• Familiarize yourself with the exhaust layout to identify any bolts or clamps securing it.

Step 4: Disconnect the Exhaust System

Carefully disconnect the exhaust system to access the catalytic converter:

1. Use a socket wrench to remove the bolts connecting the exhaust pipe to the catalytic converter.
2. If there are any clamps, loosen them with pliers.
