Congrats on the car!
Before i offer my advice, i need to ask, what is your emissions testing like in CT (saw it in your bio).

If you are simply looking for more sound, buy a NON VALVED cat back system, or simply remove the resonators. If emissions testing is not a concern where you live, get rid of the cats. Forced induction cars arent really meant to have cats, as they will literally melt under prolonged use.
