Sorry, all I can hear in that video is the typical tinny rattle that the Flowmasters always give you. Makes me want to look for exhaust leaks and check the valve lash. Always sounds like somethings broken.
If that's with the pipes ending at the axle you'll probably get a little less rattle with the full pipes, but you'll end up with more drone inside, even though it will probably be a little quieter inside the car.
I honestly don't care if it's it unicorn mane, it works. ;)
