Stock cat links to turbo, but universal HFC is relocated after downpipe, am I right?
I don't know the first thing about even the stock location for the sensors. Could you please enlighten me?

hfc = replaces the normal cat just after the turbo
one o2 sensor sits up top near the turbo (in the cat though) the other one goes down near the bottom of the cat towards the driver side
HFC = bolt on replacement for stock cat

No they had a custom DP that came off the turbo replacing the cat and most of...
the factory DP. Then the area where the flex coupling normally located that is where the cat is placed.

On that scenario, would O2 sensors need to be relocated? Do the related wires need to be extended?
I see from your sig that you are running the TT DP, but is what you are running basically the same configuration? And did the O2 sensors give you any trouble?
