The last I heard, TH does not make the DP for the TTA or GN. Rather he makes the flange that he welds to the DPs that are bent in GA, (Grand Muffler).

TH assembles the DP from the bends he gets from Grand Muffler. The flange and wastegate puck assy are what TH makes. This was the case as of receint, nless TH has just bought a Mandrel CNC bender.
