Have a muffler shop use 2 1/4 inch aluminized pipe (nevers rusts) and some mufflers with at least a 20" long body with offset-inlet/offset-outlet (as opposed to offset-inlet/center-outlet, etc.). Midas makes some seriously quiet gold mufflers. I used a pair of them (meant for a Cadillac, I think) on a 57 Chevy with a hot solid-lifter 292 (.060" over 283). It was so quiet, all you could hear was the lifter tick at idle, and a pleasant subdued rumble on acceleration. Walker also has a new Quiet Flow model that's supposed to have lower restriction without the noise. If yours is a stock, low rpm engine, a single 2.5" pipe and muffler would probably do the trick. Whatever you do, use mufflers with the biggest case you can fit under the truck. Something for an old 500-inch Cadillac or 430 Lincoln might be a good place to start.
