Why did my car make a HUGE banging noise when I drop through a puddle?

Congrats... You must have a corsa exhaust. This is a known issue.

The corsa exhaust has very narrow tollerances between the exahust and the driveshaft. When you drive through a large puddle the sudden cooling shifts the exhaust and it CAN make contact with the driveshaft. This is the loud banging that you heard.

If you have this issue (and after you clean your shorts) you can have the exhaust adjusted so that it will not make contact. Take it to a mufler shop.
