Default 2004 s40 5cyl catalytic converter replacement

Does anyone know where I can get a cat converter for my 2004 s40 2.4l 5cyl (not turbo)? I was told it's a dealer only part and I cant afford $1200 for just the converter right now.

plenty of online parts stores -

FCP Euro, EEuroparts, IPD USA, Rock Auto, AZ Autohaus are a few that I've used. Also Tasca Parts is a good source for dealer parts. Just curious why you think you need a new cat converter (the cat efficiency fault code is often caused by an intake air leak, exhaust leak or a weak O2 sensor..)

I was told the code that comes up for the check engine light that is on is for a cat converter that needs replacing. The estimates I've gotten are crazy expensive so I am getting a second and if necessary a third opinion.

have the shop (or Autozone etc) scan for the check engine light fault codes and ask for a print out to see if there's more than one code. The typical cat converter fault code is a P0420 which is saying the front oxygen sensor and rear oxygen sensors signals are not correlating - which means either one of the sensors is off or the converter is not working efficiently and sometimes the sensors are off due to an unrelated problem (which may have additional codes).

fully equipped shops can scan for the fault codes, the fuel mix and even check the temperature of the converter (ie via a heat detector) and measure the values of the oxygen sensors before recommending replacing the converter. First step is to get a print out of the codes then start googling (you can read up on the P0420 code to see what I mean).
