Must be Liphardt I guess: http://www.automobiltechnik-gbr.de/3.html
But I highly doubt the gain in HP. They simply take the old ceramic monoliths out and replace them. You have to send, or take the old cat to them and they weld them in.
Their cats will also eliminate the need for an AP and all attached tubes.

I don't think that there is a single Liphardt-Kat on the road in the US.

Liphardt made this upgrade many years ago to get the 928 in a lower emissions group (from Euro 1 to Euro 2) in Germany. With this taxes are cut in half. This change is TÜV approved and comes with an ABE certification (Allgemeine Betriebserlaubnis).
I don't think that there is a single Liphardt-Kat on the road in the US.
