does anyone have stacks on there truck? i really want stacks but i dont know what size. if u have pics that would be great.

 

Stacks on your pickup ? Your joking right ?
I've seen it done with old driveshafts for pipe then painted silver or black. Also seen semi truck crome stacks used. The bigger the better. You can go 13'6" high and be legal in most places but 10' or less for drivethroughs.
Oh and don't use mufflers you want this baby loud ! Oh and you'll need a mullet.
