Greetings to my fellow TN'ers. Here is my dilemma, I filled up at a gas station on my way back to Austin, TX. Upon exiting the gas station, I heard my 02 camry scrap something, it didn't sound that bad at all. Today when I started my camry, I heard some rattling and the exhaust sounded a little funny (a little louder and hollow). Upon inspection I quickly found a bend piece of metal sticking out and was rattling against my exhaust pipe. On the driver side I could see a decent sized hole in a metal part of the under-carriage. Please refer to the pictures below. I this hole opens into my cabin and now water and dust is going to seep into the cabin. If anyone can please help me identify what has happened and how much will it cost to repair this? Any help will be greatly appreciated. Thanks in advance.
This is how it is supposed to look like (Driver side View):

This is the passenger side view. (See the bent metal plate that was supposed to be straight)
