9. A fracturing system, comprising:

a fracturing tree;

a fracturing manifold coupled to the fracturing tree by one or more valves of the fracturing tree to enable flow of fracturing fluid from the fracturing manifold to the fracturing tree via the one or more valves without the use of frac iron or a fracturing head between the fracturing manifold and the fracturing tree; and

at least one additional fracturing tree coupled to the fracturing manifold by one or more additional valves of the at least one additional fracturing tree;

wherein each fracturing tree is coupled to a shared trunk line of the fracturing manifold and the shared trunk line includes a plurality of wellhead crosses and pipes extending between the plurality of wellhead crosses.
