Hello, I recently had my CEL come on on my 2006 AP2 S2K, it came out to a P0420 error code meaning I need a new CAT and O2 sensor. I ordered the new sensors but am still looking for an OEM grade cat that doesn't cost $1000. Does anybody have a spare oem cat they want to sell.

 

I have an OEM cat w/ 50k miles on it in perfect shape still. Inner comb still looks brand new. PM or text me @ 203-927-3885 if you're interested.

 

Judging from messages here the catalytic converter rarely goes bad. Have you run thru all the pages in the Service Manual on this code?

I have a Berk 63.5mm high flow cat on my '06 and don't show any codes nor did it fail Ohio smog those times it was tested. Under $250. I had tabs welded on it so the heatshields would mount but a large chunk of concrete on the road broke the welds so I've run without it for 4 years, just the cat no shield.
