What would the best dual exhaust system for a f150 with a 302?

I would use a pair of turbo mufflers for a nice rumble, but not so loud that you attract every law enforcement person from 3 counties bordering you....2. Knuckles Says: headers and no cat with borla for performance or cherrybomb/flowmaster for sound. even with the cat, headers and new mufflers will you give you some extra umph through the higher rpms.
