Default Failed catalytic converters, what now?

In the last 10k miles or so, I've been able to smell a rotten egg aroma more and more if I give it some gas. I'm not throwing any codes so, assuming this is from the cats, has anyone had to replace these before? I'm a huge DIY'er and upgraded my G37 cats with test pipes, that was a nightmare. If this car is anything similar, this is going to be quite a chore.

Also, I can only seem to find pretty pricey OEM versions. Do the IS350 cats fit? Do we have any decent aftermarket high flow options or reputable OEM rep options? If not, I'm contemplating just doing a trade in for a 4th gen now lol.

Thanks
