Does putting a new headunit give you more horsepower? What about stickers?
...That is your answer.

People claim you 'loose power' because the shift in the power band is not ideal for daily driving. I never put a 3" on my car but drove a 08 OBS with 3" catless straight piped
and it felt the same as my car.
This. You will feel your low end go away, due to the huge loss of backpressure on a N/A car, but your top end will gain as there will be less restriction on the flow of exhaust gasses leaving the exhaust. All that will change is how the power reacts per RPM.
