Loud bang under the car

I'd get the car on a lift and check the exhaust system and catalytic
converter. Could be something crunches when it gets hot. It
shouldn't.

It could be your front disc brake pads moving into position, this usually happen right after you start moving forward but in your case this may happen on the right side after ten minutes.

Try moving your car forward then brake, select reverse and move then brake.
If you can reproduce the noise this way it maybe a suspension/braking
component which an observer (outside the car) maybe able to get a line on.

As mentioned before, the exhaust system maybe hitting the floor when the
motor moves in its mounts,...worth checking out.

Also a loose baffle in the muffler can make a VERY loud noise if its forced
to move under exhaust-gas pressure once the muffler is up to full operating
temp.
