I hear a rattling underneath the car after I have been driving for more than 30 minutes. It gets louder and louder. And I hear it more when I press on the gas pedal. I hear it when I'm driving next to a wall or another car, where the sound can bounce off as I'm driving with the windows down.

Take a rubber mallot and tap on the exhaust system. Check for loose heat shields or loose internal parts in the catalytic converter.
