agreed w/ the too little backpressure, but you can easily get duals, just
figgure out the surface area of (example: 3" single) vs. what that same
surface are is for 2 pipes. A lot of math I don't like to do, and you will
almost definitely need a custom job to get the duals in a specific
diameter..
by surface area, I mean the inside diameter at the smallest point (for
non-mandrel bends) in short, make sure the flow rate is equivalent with the
2 pipes as it is for a single (ex: 3") pipe...
