duals for sure...I have about 1/4 around the whole pipe that drops through the bed( it enough for my truck but you will need more since you are plaining on coating your bed). I have mine setup that I have a 6" pipe droping down from my 6x6x0.25 square tubing that runs the width of the bed( cross piece and SS uprights weigh in at probably over 200 lbs) and a 4" elbow pointed up into the 6" round pipe from under the bed and with the clearance the rain that goes into the stacks just runs out and misses the 4" exhuast elbow in the center.
You also don't want to go to small of stacks or the truck will be very loud... larger stacks give it a nice agressive sound but won't get ya introuble with the law.
