Peterbilt Motors Co now offers a single-exhaust configuration for its heavy-duty conventional vehicles powered by Caterpillar C10 and C12 engines, the company announced.
The new configuration — which reduces vehicle weight by 100 pounds versus a dual-exhaust configuration — features a single vertical muffler and exhaust stack mounted to the side of the cab, and a catalytic converter mounted under the cab.
“This new option is ideal for tanker and other weight-sensitive applications, as well as for heated dump applications in cold climates,” says Dan Sobic, Peterbilt assistant general manager. “Since the catalytic converter is under the cab, the exhaust gas can be easily routed to the dump body without violating air quality standards.”
The single-exhaust configuration is available for Peterbilt Models 379, 385, 378, and 357.
