we all have different taste, I like my dual smittys straight out the back with some chrome tips,,I love the sound of it,and have had good comments from other bolters that have heard it,,cletis, Dale 937 and others,,,,,,,,,,,,,,,,,,,,hey I have an idea, how about dual stacks behind the cab,,, their is a local guy that has a 54 GMC and that is what he has, sort of like a big rig,,many will have different opinions but I like mine the old fashion way, straight out the back,,,,,,,,,good luck,,,,Fred
