Not true dual exhaust, no sound difference with stock mufflers and no hp/tq difference either.

Why did they even bother redesigning the exhaust for no power gain?

There is a power gain. You can't dyno cars after 10 years they come out and prove there are power gains from the LSC piping because the engine's are in different conditions. I think Lincoln advertising the LSC model at 290 vs. 280 for the base is a fair assesment. You gain about 10hp at the crank going from the base exhaust to the dual LSC exhaust. You are better off getting custom piping though, 2.5 inch dual piping. I believe the LSC piping is 2.25 inches.

can someone post a pic of the LMS exhaust system from underneath?

Heres a pic of Gaurdian Car Care custom exhaust!

is that only one muffler? Looks like it would be loud.

At idle it is very quite, but at WOT it screams! Similar to the LMS exhaust.....
Heres a clip, sounds loud once you press on the gas......http://media.putfile.com/markVIII-01799

The Magnaflow mufflers off a nice subtle rubble while in the city, and while at steady hwy speeds. But when you step down on the peddle to giddy up and go the have a very nice roar. Very fitting of the class of a Mark VIII.
