Cats just can't handle the heat, at least not in the stock location!

The only cars I've seen that have issues with cats are the ones that aren't hitting AFR targets. Too lean or too rich will cause problems. I've tuned several with STOCK cats and aftermarket cats and all of them are still doing just fine, even with upgraded impellers, pulleys, etc.
