What they said about quieter mufflers. Lots of them out there. Even a few from the performance companies like bronconut73 was saying about his Flowmasters. Just be careful when going that route! The wrong choice will put you right back where you were.
Personally I prefer the single exhaust, or, like mine is currently, dual exhaust down the passenger side.
Either way keeps the fuel, electrical and brake lines away from any excess heat. And usually makes it easier to work down the driver's side on just about everything else too.
But since it looks like your current exhaust system is pretty new, if not brand new(?), then just opting for two new mufflers will not only most likely get you at least closer to where you want to be, but also be MUCH less expensive than replacing the whole system.
If there is room (there often isn't in a dual system on an EB) then I would also have them add a crossover tube between the two sides. This helps in several ways.
You'll hear similar things called "H-pipes" or "X-pipes", but those are only if the two sides have a point that's so close together as to almost touch. When they're as far from one another as they usually are on an EB, a "crossover pipe" custom made to your system is the only way to do what the other items do for other vehicles.
That last bit is not mandatory. But Ford engines do seem to respond very well to linked sides to balance the pulses a little more between the cylinder banks of the engine.
Up to you, but at least get some quieter mufflers on there.
It won't be "stock" sounding, and might not even be close to that as you want, but it'll be much quieter.
