Another suggestion, assuming that it will work with any government emissions requirements that you have ...

install long tube headers, no cats, and late model stock exhaust. there is no drone, almost stock quiet in the cabin, and a decent sound (subject, I know) behind the car. My current setup is SW headers, no cats, and stock exhaust from a 96 LT4 (h-pipe behind the resonator) and it works well for me.
