Replaced my wife's cat a few years ago in an Integra cost a little over $400, $350 of it was the cat alone. Took it to a little shop in Escondido.

Cats on my 05 X cost about $2,300 for all three installed...and two failed 3 years later.
Should have lasted 10 years...
Get factory cats and find a reputable mechanic to do it right the first time.

. I have family at a dealership and got the two cats at a decent discount for my 2004, $800 and installed them myself.

At the risk of seeming naive, what could be the problem with using a factory part from a junk yard. They could be brand new if a car has a crash shortly purchase. If it makes the vehicle pass smog, it should be no ones business where the cat comes from, the final outcome should be all that matters.

CARB regulations are such a joke. You're preaching to the choir around these parts. Why can't they just set limits on how much pollutants your vehicle is allowed to emit, and not worry about anything else? Micromanagement = $$$ for the system, and shops will exploit those regulations to get $$$ too.
Like the whole concept of automatically failing a smog test if you have an illuminated check engine light, even if the car pollutes less than a fart from a church mouse. Or like the stupid fuel can nozzles that are supposed to keep fumes from escaping, but make you spill more gas than the amount of fumes that would have escaped.

. What happens that you know they need replacing?
With my 05' Xterra, it literally stopped running. I thought it was an injector issue, as it was sputtering and power diminished as it got worse. Limped it to the mechanic, and had the cats R&R from there.
From what I understand, engine performance and mechanical issues can contribute to the demise of the catalytic converter units. In my case it was the IPDM relay issue that supposedly caused my cats to clog and fail. But honestly, I think catalytic converters are frikkin' expensive unicorn tubes made to f*ck you out of useful mod money.
But I'm not bitter. >:D

Do all 4 fail or is it often only 2 need replacement. Does anyone know any fail pattern, I have 160,000 on my X and don't think they have been replaced and I am not sure how to tell. What happens that you know they need replacing? Can you junkyard source them?
Typically it's the two upstream cats that go. Mine was due to running rich for too long, which was a result of a slowly failing coil buried inside the dizzy. Not a problem you second geners will deal with, a lazy coil pack maybe. I was at 204k when it went out. Sometimes they clog and the back pressure causes the engine to run like crap, sometimes you get the rotten egg smell. And sometimes you get an SES code from your downstream O2s. YMMV
