THis is a school bus- Exhaust downpipes leading into the catalytic converters melted down and created large holes in the exhaust pipe itself. Extreme heat developed by engine.
School buses. We have a fleet of these and the condition is happening repeatedly and to almost every bus with this PSI brand 8.8L gasoline engine. The engine exhaust downpipes melt from excessive heat and/or fuel. The pipes then crack and produce an exhaust leak near the body firewall. Potential for exhaust and flame to escape from the pipe.
