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.

I live in the UK, our dynos always seem to read lower than US ones, IIRXC it was around 1-2bhp.
Berk did a big test against oem/tp/hfc
hfc came within 1-2 hp of the tp, which meant about 4-5hp gain, so tp could net you 5-7hp

And what's IMO ???

I dont think it would hurt anything to just throw it on without a retune

Of course you got a tune for a car with a cat, if you still want a great tune for your car you need a retune when you change something
