Dual stack exhaust system

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.

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 collector disposed in the truck bed, the collector having an inlet and a pair of outlets, with both of the outlets being in fluid communication with the inlet;
• a 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 inlet of the collector through the opening in the bed of the truck;
• a pair of generally vertical exhaust stacks each having first ends in fluid communication with one of the outlets of the collector, the stacks extending upwardly to open second ends.
