I'm guessing you are talking about the 2 different outlet styles? One is a T31 housing (T3 inlet, 2.5" outlet) and the other is a Garrett GT housing (T3 inlet, 3" GT outlet).

I don't think there would be much of any difference since all the downpipes made for a T31 housing quickly flare up to 3", and all the Garrett GT-Style housings still has the same size turbine, but simply has the "flare" to 3" cast as part of the turbine housing.

It seems to be "6 of 1, 1/2 dozen of the other."
