Dual stack exhaust system

摘要

A pickup truck and exhaust system combination is designed for a pickup truck having a cab and a bed extending rearwardly therefrom. The bed has a load floor bounded by a front wall adjacent the cab and a pair of side walls. The bed has an opening defined therein. The truck has an engine and an exhaust pipe extending rearwardly under the cab to an outlet end. A flexible exhaust coupler has a first end in fluid communication with the outlet end of the exhaust pipe and a second end in fluid communication with the first end. A hollow elongated collector is disposed on the floor of the truck bed adjacent the front wall. The collector has a first end and an opposed second end with the midportion therebetween. The collector also has an inlet defined in the midportion, with the inlet being connected to the second end of the coupler through the opening in the bed. The collector also has a first outlet defined in the first end and a second outlet defmed in the second end, with the outlets being in fluid communication with the inlet. First and second tubular exhaust stacks have lower ends connected to the first and second outlets and extend generally vertically upwardly therefrom to open upper ends.
