Be sure to confirm the cats are in need of replacement with a post cat emission sniffer check and physical examination. It only takes 15 minutes per side to remove and confirm their condition. I am guessing the ceramic cores have broken loose from the housings...that is the usual failure mode. Post picks when you get them off.
