I agree that external WG have advantages but there are packaging considerations as well. Internal waste gates are adjustable which can help offset other weaknesses. The above system has the WG venting back into the muffler so may as well use internal unless just to big/powerful.
I also use dual TiAL 38mm WG on higher HP systems that must have precise WG control. Have made several of these and really like the packaging and control.
