Quoting TylerAdamson:
The step is to seat the wastegate properly.
Here is a picture of the inlet side of the 44mm TiAL and you can see the step on the wastegate.
That step is from the valve seat ring. The mounting flange of the wastegate on the manifold should be a flat surface. When the wg is mounted on a flat surface flange, the valve seat ring will then be pushed in to preload the valve a little bit to make sure that the valve is fully seated and have no leak. If the wg mounting flange is stepped like the one in OP pictures, then the wg valve seat ring will never be pushed inand will prevent the valve from seating all the way. The outlet of the wg is stepped though, as you can see on the tial picture because the dump tube flange is also stepped to make registering/ centering the flange easier. What I think happened is that someone use a stepped flange for a dump tube as the wg mounting flange on that manifold. Need to cut out the manifold wg flange and weld the right flat mounting flange on that manifold to make the wg valve seal properly.
