Definitive EcoBoost Exhaust Sound Thread

Just from a purely exterior sound.

Was just reading another thread in this forum and some people don't have drone issues (doubt the drone isn't there) and some people that call it head rattling. Back to my original post, resonator is the way to go. Apparently the stock mufflers also aid in some of the resonance cancellation, and removing them is bad news for your sanity. Hence my original thoughts of someone building a resonator on an open exhaust (Helmholtz resonator)....and just looking up Helmholtz resonator SHO...and found this gem...honestly, the best sounding 3.5EB exhaust I've ever heard.

Anyone have a clip of PPE catted downpipes with muffler delete and/or resonator delete? just pipes after the catted downpipes?

If I'm honest these videos seem to minimize the drone...it's probably a little worse then the video makes it out to be although I haven't listened with headphones. I hit the turn signal so you would have a reference noise for comparison...
 
Trying out this Chinese knock off go pro don't know what happened with the audio when I was reving.

3rd cat and resonator delete with 2.5" straight pipes. Very quiet in the cabin no drone at all.

2.5" catless downpipes (LMS) to 2.5" stainless double x pipe and 4" quad tips.  No cats or mufflers.  Exhaust revs near end of video.  I let it warm up first.

That definitely sounds mean.  Gotta love hearing those turbos whistle even more now I bet.  Thanks for sharing!
