I have a stack manifold that is made from 2 by 6 rectangular tubing with the ends capped off and a 4 inch piece of pipe welded in the bottom of it. The stacks are currently just welded to the manifold but I am trying to come up with a way to make them interchangeable. There are 3 steel bars welded to the bottom that bolt to the bed. They are solid.

Napa sells the elbows. I bought a 90 degree elbow 16" x 16" and 3 foot of stainless flex and did my own stack just 3 days ago.
