350,000 miles on my Stock Corolla exhaust from 1995 Original cats and mufflers all stock.
E10 fuel ...Yea I said that.
I have seen Ford Taurus cats give up at 110,000 miles.
Something defective with them as they break apart into gravel size chunks and larger and end up clogging the exhaust system.
I could not have an engine on a stand and keep from pulling the heads and cam for an upgrade.
