I just deleted the OEM muffler & left the resonator - replaced muffler with 3” delete pipe.
Just a bit louder the OEM - others say it sounds like a deleted diesel - decent amount of Turbo whistle.
Nothing annoying @ highway speeds.

I heard from lots of people this is the way to go.

The sound quality of both recordings is absolute garbage. Sounds like one recording was from the rear and the other one from the glove box.

0 to 60 in 3 to 5 days. Just get the Ford V-8!
