2006 Pacifica Catalytic Converter
 

Whats going on guys. Got a check engine light and my scanner gave me a code and description for the catalytic converter. Has anyone replaced one before. Im an aircraft mechanic but not too familiar with cars. Just recently decided to do my own maintenance since I got my garage with a lift. Any suggestions on parts and tools I would need or how to check to see if I actually need to change it or check for leaks?
