Exactly!
Another thing I forgot to mention...what's weird is that I passed emissions about 1 week before my check engine like came on and the dealer said both my cats were bad. Don't know much about emissions testing, but if the cats were that bad seems odd it would even pass.
Thanks to those who have replied. Like I mentioned there's several "yeah buy aftermarket" posts out there, but few that follow up after they are installed and ever fewer, if any, that confirm they work years later.
Thanks again! Any additional info and opinions are always welcomed

I hope you saw the humor in my post and didn't take it critically...
I kind of disagree with the formula Pluton gave because of the scales involved. The OEM cats are in the range of 7-8x the cost of an aftermarket one ($300/pr vs about $1k each). Pluton said his lasted 2 years, which is just 1 data point and says nothing about the actual lifetime of them, I mean mine are over 2 years now, and I dont' see others saying that their aftermarket cat;s are only lasting 2 years. Regardless, you just aren't going to overcome the price difference of OEM cat's, especially considering the age of these things, so if the OEM ones are really stating to fail around 15 years, the what is the likelihood of the 4runner lasting another 15 years in your ownership? Even the hardcore fans here likely won't have them in 15 years. You'd HAVE to keep it the entire 15 years to make your money back.
