Difference in open mouth and twin port?

the twin port is supposed to keep the gases seperate from the wastegate and the main turbo exit so the air is less turbulent and flows and exits faster. does it work? god knows lol. harvey smith (r.i.p) would have been the man to ask as he was a bit of a guru with exhausts and trick up pipes and porting headers and turbos etc.

dont think it really matters bud there,s probably arguments either way which is best.

I have both, but I have my twin fitted at the moment, did see a YouTube vid showing the twin was better or you needed a separator plate for the bellmouth but how much difference it makes I don't know,

do a search for any posts from harvey, he might have covered the subject in the past.
