Good question. For the Eldorado maybe the cat has something to do with it, maybe the mufflers are different. Maybe there's just no room under there.....!
Buddy of mine did a 3" Flowmaster job on a 2001 STS and left the resonator off - and it's LOUD, so that's where I'm coming from.............
As far as the true duals, there just isn't any room in that small tunnel, and the FWD cradle and frame are low enough without a bunch of pipe and 2 convertors hanging down another 2 - 3 inches. Damn, it would be nice........
