what makes the gases go out? negative pressure? vacuum?
Think of it as collected volume under pressure.
On-throttle exhaust gasses fills the chamber as they're being ejected from the exhaust pipes. Once the chamber is full, the exhaust gasses maintain pressure in the chamber. When the driver goes off-throttle, the collected volume is released due to the release of pressure within the exhaust. The release from the chamber provides added exhaust volume to off-throttle blowing.
The effect is not massive. It just helps to stabilize the transition.

Are teams forbidden from adjusting the diameter anywhere along the length of exhaust? A simple pinch somewhere is all that's needed to adjust back pressure.
