Thanks for that. The other thing I'm wondering, is if you move the cat back, it won't be able to reach operating temps, no? Florida isn't one of those states that tests, but this would be a major headache for those states that do. Plus, even with the 100-cel cats, you'd probably have stink to tolerate if they don't get hot enough.

You're right...I'm overthinking...

The reason to move them back is to get them out of the way of the much higher temps that the cats would see in a FI application. Moving them downstream will still be hot enough for them to light off. These work very well. This isn't something to have an issue over.
