Definitely better off using a tuned resonator when going muffler-less.  The 3.5 is not a cool-sounding engine.  PPE + Corsa should work fine though.

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

My single biggest gripe about this platform...I have yet to hear a "good" (obviously it's subjective) exhaust. Stock, my Flex has a nice throaty growl from the driver's seat. My dad's stock '16 F-150 has that awful tinny/rattly V6 noise.

Now I think you are absolutely right about the resonator. After years and years of exhausts and research, I think the single biggest mistake people make is with resonators. As much as most people will deny it, Ford engineers are really good at their job, and that resonator is there for a reason. And that reason is to even out the exhaust note and prevent drone, probably the two biggest complaints when people start messing with the exhaust.

Reminds me of another forum I was on; some kid decided he wanted a little more noise out of his ex-cop '16ish DoD Caprice. He said all was fine, until the car went into econ-mode (4 cylinder) and the drone was unbearable. He said he left everything stock (INCLUDING THE MUFFLERS) but ditched the huge resonator. Well, that resonator was big for a reason...it not only was working to combat the resonant frequency of the 8 cylinder mode, but ALSO the 4 cylinder mode, keep NVH down during all modes of driving.

I don't understand why turbos on these cars change the exhaust tone/type SO much. The Duratec, which the EcoBoost's are loosely based on, had really pretty nice exhaust notes if done right. My SVT Contour sounded REALLY good...I think it's going to take someone with a lot more knowledge about flow dynamics and resonance than me, to solve the EcoBoost exhaust high performance exhaust epidemic.

they sound pretty darn good with a Corsa exhaust IMO.  I just have a hard time paying 1500 bucks for some pipe and mufflers. but someday after DPs ill probably do it.

Just muffler deletes, IMO, sound just about as "good" as the Corsa. And it's free.99

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?

Went through this whole damned thing.  Trying to find Catted PPE DP with the Magnaflow cat back.  Does that sound clip exist?
