2015 Expedition Muffler Exhaust System Suggestions

[gsoublis]

I just purchased a 2015 Ford Expedition and was hoping I could get some opinions on a muffler exhaust system and what options are out there. I understand that I will not get the same tone out of an Ecoboost but I want something very aggressive sounding. Manga flow sells a cat back system but it shows it has a moderate sound. I then looked for a Flowmaster 44 and found that on turbos you need to have a straight through muffler system. I don’t want to impact performance or cause a negative back pressure issue. What are your setups suggestions? How is the sound and any issues? Thank you in advance!
