At least a portion of my cats got blown out the mufflers the first dyno pull after my A&A kit was installed. I never had them changed, but will eventually swap them out for high flow cats. I suspect the ones I have are still doing something at least.

I had my replaced on my LS2 2005 Corvette, right was clogged, and brought on check engine light, and when they checked the heat right exceeded 400 degrees, while left was less than 200 degrees.
The mileage was 73,000 in 2019.
