That is complete BS. The 3.5 Ecoboost doesn’t use an EGR it uses VCT.
OP you’ll be fine removing that muffler if you want
Huh... VCT has nothing to do with it, but indeed no EGR.
Good work Ford, surprised they managed to pass emissions without EGR on a 100+ hp/ litre forced induction engine in this day and age. I thought it was unavoidable in this day and age.
However.... back pressure affecting turbos is still a concern. It should get nore boost than it does with an intact muffler, idk whether or not it has the ability to adjust it accordingly
