94 Civic - how long does cat last?

I have 180k on the civix 1.5L LX 5spd sedan - I think I am the 3rd owner.
I am changing out the exhaust with an equivalent - I was curious - how long
does the catalyst last?
thanks

If it has never been changed, it's probably due. Symptoms typically are
a loss of power..

Is there someone that can check it if I remove it from the car?

 

The samples that I've seen were obvious, tip it vertical, and the
innards partially will fall out. I'm sure that others here will
elaborate further.

If the car is cared for, the cat will easily last 250,000 miles. If the car
has been neglected, it will last far shorter. If the car is neglected
enough, the cat can clog, but that's a "worst case" scenario.

 

Take the car for an emissions test. That's the best way.

 

well, he's gonna remove the cat-back exhaust anyways... you can actually
shine a flashlight in thurr & if you can't see thru the honeycomb...
clogged...

coolant leaking into exhaust stream, excess blowby of oil, leaky fuel
injectors leading to excess HC(unburnt gas)--- all these would shorten
the cat & o2 sensor's life...
