Hi,

According to my manual, this vehicle only has one. It should be located approximately in the center under the vehicle. I attached a pic below showing it.

Here is a link you may find helpful. It explains in general how one is replaced.

I hope this helps. Let me know if you have other questions. Also, when you get the new converter, there is likely a flange gasket between it and the flex pipe, so make sure to get one.

Take care,

Joe
