Apparatus for diverting a flow of exhaust from an engine of a truck
 An apparatus is disclosed for diverting a flow of exhaust from an engine of a truck having a truck bed and a muffler system, with the truck bed having a duct system. The apparatus includes an inlet for receiving the flow of exhaust from the engine. The apparatus further includes a first outlet connected to the muffler system and a second outlet connected to the duct system. The apparatus additionally includes a diverter member positionable between a first position and a second position, wherein (1) fluid communication between the inlet and the first outlet is prevented when the diverter member is positioned in the first position, and (2) fluid communication between the inlet and the second outlet is prevented when the diverter member is positioned in the second position. Moreover, the apparatus includes an air cylinder for moving the diverter member between the first position and the second position. The apparatus also includes a sensor which detects decoupling of the second outlet from the duct system and generates an electrical signal in response thereto, wherein the air cylinder moves the diverter member between the first position and the second position in response to generation of the electrical signal. A method of directing exhaust from an engine of a truck is also disclosed.
