2011 Cadillac SRX: $1900

2010 Mazda 3: ~$1200

So I would definitely guess it's in the $1k range. As far as I'm aware, the issue isn't the part cost. They require quite a bit of labor to replace, which drives up the price.

No clue on the O2 sensor issue. But I know that in both cases for us there was no doubt that it was the catalytic converter causing the issue once the mechanic (whom we trust, and has always been fair) looked at it.
