car makes loose banging noises?

[In$4n3_625]

I went over a random pothole going to school, now when ever i go off my driveway or hit little bumps and what not i hear noises as if something is loose and banging around, im not sure if its my exhuast pipe or the underside struts, i poked around the pipeing and whatever with a broom and nothing seems to be loose, what could be the problem? I have a 97 acura CL by the way
