Bobby, is your car an XK or XKR?
Have you done any air intake modifications like a K&N filter?
How many miles?
Do you have a scanner that can read specifically fuel trim live data?
Have you had the intake manifold removed for any reason (coolant repair) or the intake gaskets replaced? If so, how long ago?

The only useful evidence thus far is the new (oem) O2 sensors. It would be helpful to know which codes are you throwing which causes the failure. Additionally, what is the statement in the failure report?
Without evidence, you will continue to play the musical parts game. You might get lucky and hit a hole in one. But it is an expensive path for 'lucky'.
And apologies, I had a different thread in mind when I suggested the new cats. I would want to see evidence for the need for replacement.
But your car is an '07... and if you have as many miles as me... well, I'm on my 3rd set of cats.

Can't pass the emissions test and I'm looking at the converters. I don't see the logic in your statement; it's nothing like replacing an entire engine are you kidding

He posted once. Let's see if he comes back and defines "everything" he tried and includes codes. Without codes, this thread won't be helpful as you know.

In terms of throwing around $1000 bills, the OP has already done that, saying he has replaced O2 sensors with OEM parts to no avail, and I cannot imagine this being a cheap process. As a 2007, the convertors are on the better side of 16yrs of age. The whole purpose of catalytic convertors is to reduce harmful emissions. I do not know why you are getting so worked up about this.

My previous Jaguar (1993 XJS 4.0) couldn't pass its California tailpipe emissions test.
I had a muffler shop cut out the old catalytic converts and weld in new, generic ones for a couple hundred USD each.
The car then passed with flying colors.
Carparts.com and others sell just the converter without the exhaust pipe. Unless your pipes are rusted out most muffler shops could make the change for you for the cost of labor.
