no not much driving it was a bosses bus.
its a vaccum operated diaphragm on the exhaust, so when your foots off the accelerator and not clutch the diaphragm closes and forces the gasses out a small oriface in the exhaust pipe its self causing a restriction which slows you down effectively. and its on a switch for when you dont want to use it
