Joe,
Sorry for letting you down.
Rusty Rod and others,
The stacks on the truck I saw were just chrome exhaust pipe run up the back. Not those big things with a bug zapper screen wrapped around them.
I would probably never run the exhaust like that, but it looked cool on the truck in the magazine. Kind of like the way some of the old school bikers run long exhaust up the back of their bikes. Another way to express oneself!
