I have a non-EGR 1993 240 wagon. I replaced the catalytic converter in 2015 with a unit I found on FCP's website. My receipt says it's a DEC VO3522. It fit perfectly with the factory header.

This was the second cat I tried. The first from FCP was a different brand and did not work b/c of the floating flange on the header pipe (their website said it was compatible!).

I see the Magnaflow unit on FCP's website and it's not cheap.

I recently thought I would need to replace the cat on a 2002 V70 (again, not cheap). I looked for other solutions and found Cataclean. I followed the instructions exactly as on the bottle. The CEL vanished within 30 miles and has not returned after 1k miles. I call that a success (at least for now!).
