no, you will gain power.
Consider a high flow cat, it makes about the same power (-1 hp or so)
you will also need to retune, because it will lean out your car a good point

Has anyone discussed the long-term fuel trim ramifications of a TP? I've searched and didn't see a whole lot. Sure, an initial dyno will gain power due to the LTFT being @ the settings for a cat, but is there proof of sustained gains from a TP??? I'm concerned that as the ECU learns that any gains would be lost.

Anyone tuned who changes something to do with the engines performance (in this case installing a TP) should get retuned to truley reap the benefits.
IMO retune is a must

You will gain a small amount but not much, the stock CAT is a highflow to begin with.
Highier flowing CATS IMO will add next to nothing on the F20C or F22C n/a wise.
