Also, Ford must be some sort of wizard when it comes to exhaust, because the Stangs consistently have one of the sweetest sounding exhaust notes out there. I love to ride around with the radio off and the windows down, orchestrating my own private symphony with the subtle pressures of my right foot.

I think the sound comes from the firing order. The 4.6 uses a traditional 1-3-7-2-6-5-4-8 firing order which is the same as the 5.0 firing order. The GM LS series uses an unconventional 1-8-7-2-6-5-4-3 firing order and I believe this is the reason the Mustang tends to have a better sound. Having owned several LS engines and currently having an LS3 there are ways to "tune" an LS engine to make it sound better but side by side my Mustang with Borla's sound a heck of a lot more muscular than my LS3. Now performance is a different story....
