It looks like you're pretty much done with the project, but what may have been easier (maybe) would be to buy a used o2 dump, cut off the dump tube and weld an external wastegate off that so then instead of having to add material to where you cut you re-circed Megan housing there would already be a clean downpipe portion. This way it'd atleast look nicer since the dump tube was already seperate.
Defaintly took some hard work, cutting away at the cast turbine housing. Something I would have NEVER done... Props

I thought WGAs help keep boost to redline not really wastegates but...I don't know much about wastegates, can someone explain the difference between external/internal besides the fact that external is louder and which would do a better job of holding boost to redline?

when you run an o2 dump its the same as a regular o2 housing and theres an open chamber to allow room for the wg flapper to open, then when the flapper opens the gases are just dumped through the tube vta... so if you continue to run an 02 dump but cut away the dump tube and mount an ewg right to the flange and remove the flapper the exhaust gases are going to be mixing below the flange in the chamber i mentioned earlier so it wouldnt be a true "twin scroll" set up... understand? or am i worng in my thinking
