Bottomed Out Pretty Good, What to Check?

[JDMLOL]

Bottomed my car out pretty good this morning on an unexpected bump on these crappy NC roads. I had three passengers (carpooled to work) and was going about 70ish mph. My car made a pretty nasty noise. The car still drives and looks fine. Just did a quick walk around after I got to work. What should I check once I can get it lifted with my crappy little travel floor jack when I get back to my apartment?

Rear axle, mid pipe, mufflers.

pretty much what jng2985 said. Hopefully most of what you heard/felt was the bumpstops hitting hard. I'd also take a look around the oil pan just to make sure.
