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.
4-5 hp/tq across the powerband

proven multiple times. Is that alot? no, but for this car... yes

I live in the UK, our dynos always seem to read lower than US ones, IIRXC it was around 1-2bhp.

atleast 4-5hp, even more up to 7hp

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

a re-tune should be much cheaper, and it shouldn't take more then 4-5 runs to tune WOT only.

If you're doing partial throttle or a complicated turbo setup then expect to rent out the dyno for the day.

IMO: In My Opinion

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
