Flowmaster 50 delta flow
3.5 ecoboost I've been told this will give the deepest tone without being overly loud. Which muffler will I need for a straight swap with the OEM.

Assuming that you have the 5.0 Coyote and not the EcoBoost, you won't be disappointed.
I have had the 50 Series Flowmaster on my truck for about 7 months now and love it. It is the single 2.5" inlet with dual outlet, and I left the resonator on. It gives a deep throaty sound with acceleration, and very minimal drone at highway speeds.
