Yeah, that's good too. If the exhaust can't leave it screws up everything. The cat degrades and starts to slowly restrict the exhaust flow as it does the engine begins to lose power and run rough. Sooner or later it closes completely and the engine will not start. Kinda like the old banana in the tail pipe, though we always used potatoes when I was a kid
My ex's 4Runner had this happen at about 150K. It was surprisingly inexpensive and easy to fix. About $150 on line for a new (after market) cat, jack up the front end, four easy to reach bolts, remove and replace the cat. I think the whole job took an hour. If you take on this job make sure you check the new donuts (washers, they should come with the new cat) and do not install them backwards. According to her manual they'll work but leak within a couple K miles.
