Honestly you will not lose HP with TP v stock cats, I ran LTH & TP and kept the same power as stock cats, just have to tune it for a more open exhaust.
The issue with HFC & I believe RTP is they will break down and could clog the exhaust where stock cats, LTH, and TP do not have this issue. LTH & TP are just straight pipes & stock cats versus HFC have better heat control that do not break down as quickly.

I remember a few places talking about making better HFC that can withstand the heat of boost, but nothing ever materialized from it that I remember.

Over the past couple years I've run 3 different exhaust setups while running the same FI resontated test Pipes. Tanabe, Amuse, MXP. I'm still GTM Stg1.

Tanabe Touring Medallion, Amuse R1 Titan both use Y-pipes. MXP is true dual. I've never done dyno tests to prove my theory but i swear the Y-pipe exhausts felt faster. Felt like the car got into boost quicker and just felt more responsive.. Just my anecdotal 2 cents..
