Dual stack exhaust system
First Claim
1. In combination:
- a pickup truck having a cab and a bed extending rearwardly therefrom, the bed having a load floor bounded by a front wall adjacent the cab and a pair of side walls, the bed having an opening defined therein, the truck having an engine and an exhaust pipe extending rearwardly under the cab to an outlet end;
a flexible exhaust coupler having 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 disposed on the floor of the truck bed adjacent the front wall, the collector having a first end and an opposed second end with a midportion therebetween, the collector having an inlet defined in the midportion, the inlet being connected to the second end of the coupler through the opening in the bed such that exhaust flowing from the second end of the coupler flows into the collector, the collector further having a first outlet defined in the first end and a second outlet defined in the second end, with the outlets being in fluid communication with the inlet such that exhaust flowing into the inlet flows out of the outlets;
a first tubular exhaust stack having a lower end connected to the first outlet, the first exhaust stack extending generally vertically upwardly therefrom to an open upper end such that exhaust introduced into the lower end flows out of the upper end; and
a second tubular exhaust stack having a lower end connected to the second outlet, the second exhaust stack extending generally vertically upwardly therefrom to an open upper end such that exhaust introduced into the lower end flows out of the upper end.

Abstract
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.

10. A dual exhaust stack conversion system for a pickup truck having a cab portion and a bed extending rearwardly from the cab, the bed having a load floor bounded by a front wall and a pair of side walls, the truck further having a front mounted engine and an exhaust pipe running rearwardly under the floor of the bed, the conversion system comprising:
-
an elongated manifold having a pair of opposed ends and a side wall extending therebetween, an inlet being defined in the side wall and an outlet being defined in each of the opposed ends, the manifold having an installed position wherein the manifold is disposed on the floor of the bed adjacent the front wall with the inlet directed toward the floor and the outlets directed toward the side walls;
an exhaust coupler having an inlet and an outlet, the coupler having an installed position wherein the inlet is connected to the exhaust pipe and the outlet is connected to the inlet of the manifold through an opening in the floor of the bed; and
a pair of elongated generally tubular exhaust stacks each having an inlet end and an outlet end, the stacks having an installed position wherein the inlet ends are each connected to one of the outlets of the manifold and the stacks extend upwardly away from the floor;
wherein when the manifold, coupler and stacks are in the installed positions, the conversion system provides a pair of upwardly extending exhaust stacks in communication with the exhaust pipe of the truck. - View Dependent Claims (11, 12, 13, 14, 15, 16, 18, 19)
