Hit Something on the highway.

I hit a large, what seemed to be, metal object the highway, I couldn't avoid it. It sounded like it hit the tire. and then the undercarriage of the car. It was VERY loud. The object had a right angle on it, looked like a brace of some kind. About 8-12 inches long.

I checked, I cannot see ANY damage at all. The tires are holding pressure, no apparent damage to the tires either. I then drove the car another 175 miles after confirming there was nothing apparently wrong.

Do you think I should bring it into the dealership? The car is about a week old. It's a carolla hybrid SE with 300 miles on it.
