2 questions I wasn't able to answer while reading other threads.
If this was replaced under warranty, and Toyota is aware of the issue are they replacing the exhaust manifold with the same OEM part, or has it been upgraded not to crack?
Also, does the cracked manifold affect performance?

I doubt if affects performance.
It doesn't throw codes or affect emission tests, either. Add to that the fact that it's very hard to observe the assumed cracks directly, and I remain a little skeptical that we can say with certainty that the ticks are a definite result of manifold cracks.
YMMV
