With your setup, you're more on the 'high end of medium' if that makes any sense. Magnaflows are excellent for performance and have a nice savage snarl to them, but they don't make your ears ring when cruising out on the highway like some shorty glasspacks or chambered mufflers would.
Realistically, to tone down the sound even more without losing performance would be to add a second set of glasspacks in series with the existing Magnaflows. Call them resonators if it makes you sleep better. This is precisely what most manufacturers did with their factory performance exhausts. The good news is, despite the added expense and complication, a straight-through muffler like this won't hurt performance at all, unlike a factory type muffler, or even a turbo muffler. Even the cross-flow transverse mufflers used on the big-block Mustangs will steal some power, and that's nothing more than a big tin can.
Given the rest of the cars on your list, your Mustang's exhaust tone must feel earth-shattering in comparison!
My Cougar has turbo mufflers on it, and it's still loud enough to set off car alarms when I go up ramps in a parking garage. Of course, I'm childish enough that it still seems funny to me most of the time too though...
One last note: Chambered mufflers stink. They have nothing of the mellow "I smoke cigars and drink bourbon" growl of the Magnaflows. They have a hollow, empty, tinny tone, and at certain RPMs, they ring like a gong, making your ears want to bleed. I *hate* chambered mufflers. Glasspacks (perforated pipes, wrapped in steel wool and fiberglass, in an outer shell) damp the high-pitched tones, and smooth things out, without all the resonance. Want more damping? Get longer glasspacks! A straight-through muffler of this type can actually flow more than an exhaust pipe with the same inner diameter, because there is less turbulence inside. That's awesome for performance, and they're cheap besides. If your system's just a little too loud, this is definitely the route I'd take, unless you want to go more nostalgia, with a crossflow transverse muffler.
I smile a lot. It makes people wonder what I'm up to...
