Do the Raptors, Harley Davidsons, and Lariat Limiteds all share the same basic exhaust (except for minor differences in tip design)?

Or is the Harley's significantly different? I read that the Harley Davidson edition has a uniquely tuned exhaust, with dual exit pipes, though I don't know if that's just at the tip (cosmetic) or all the way back.

Anyway, has anyone compared the 3 exhausts before? Do they actually sound different?

 

I looked at the Harley at the dealership and it had a massive tub of a muffler with a si/do configuration. Was hideous looking, not like the Borla systems they used to put on. I'm not sure how it sounds though, probably slightly meaty esp when you goose it.
