Exhaust exit possibilities

It seems like most are running a standard GT dual exhaust out the back, or dumping after the axle. Anyone else with other options out there?

I wonder what it would look like to try a late model Corvette system on an early stang - dual exhaust through a cut out in the middle of the rear valance. Has anyone seen or heard of someone doing this?

The Vette exhaust looks pretty good. I guess you'd probably have to replace the gas tank with a cell for fitment reasons...? Anyone with Photochopping skills who could test it out?

Both of those look good. That Shelby is interesting. I was thinking something more like this, without all the black plastic crap around the pipes - just a nice cutout.
