"break in" hahaha sorry thats funny. i have never heard of a tune breaking in. of course its going to get louder, my dad was always complaining how loud my car got when i went stage 2.

it would help us know what kind of a CBE you have and what dp you put on... i have a perrin dp i am thinking about selling that is catted and sounded great matched with an agency power CBE

you will not mess up the tune and the flow won't change much or if any at all if you were to put in a high flow resonator. that should help with the raspy sound.
