how to repair my exhaust at the front of the car

What is your question?

I drive a v6 94 camry and it has 180,000+ miles. my exhaust pipe shifted the other day and it dropped lower to the ground and while i was driving yesterday i tried to avoid a pothole manhole combo and failed, and as a result the exhaust fell to the ground and drug about a block until i could park. I jacked up the car and got a coat hanger and got the pipe off the ground but there is not a gap at the front of the system. I looks like a y shaped exhaust pipe leading down from the engine is connected to the catalytic converter by a wire mesh that apparently blew out. it looks like a flex pipe? I was hoping to figure out how to jack up my car and fix it my self, but i need a better visual reference online and general instruction if this is a realistic diy repair. I want to make sure the flex pipe is the right part as well. please help! thank you!
