De-cat question

As an owner of an Alfa of just one week, I wish to free up some power on my 2.0L - but dont really want to make the car much louder. I am aware that an effective mod is to remove the mid section siliencer or de-cat the car. Am i correct in assuming, out of the two, the cat bypass is the most effective?

If I keep all the silencers in place and install the decat mod (straight pipe) would I achieve my aim of more BHP without significant change in volume?

How many horses would I free up?

Hey mate,

I've decatted and removed the front muffler on my car and I reckon the decat might have made it louder than removing the muffler.
