If anyone can find these let me know where, I can't find them anywhere which isn't suprising given the supply chain apocalypse and precious metal supply.

Like King said, the other regular GESI cats and I think even the GEN 1 version I don't think will take that much power over the cheap aftermarket cats. The GEN 1 "UHO" (ultra high output) might though not entirely sure. I think the GEN 2 versions have more precious metal coating than the GEN 1's, which of course makes them a lot more expensive because they are designed to react more emissions then the others.
