Turning my 5.4 into True Dual Exhaust

I been thinking about how could I turn my 5.4 into true dual exhaust. Tryin to see if anyone has or knows how without buying a complete kit. I thought about buying 2 Flowmaster 40 series and having my muffler shop cut right above the "y" where it goes from 2 to 1 pipe and making pipes all the way back to where the two mufflers would go. Also I wonder since not much room if I would have the turn the mufflers on their side to fit or would that hang down too low? Any help or thoughts would help. Thanks everyone.

Wouldn't true dual require a different y pipe? Other wise it's dual to single to dual again.
