2001 Chrysler Concorde Need help please

Intrepid and Concorde are the same. Just the trim level is higher on the Concorde. The converters must be from a car with the same engine size and the same model year. They might work from a few other years too. You can ask at the dealership parts department. If what you're replacing and what you have are the same part number, they will interchange.
