you will want to make them the same size as the turbo inlet greg. Thay will give you the best result. You can get silicon joiners to go from 2" to 2.5" to match your intake

Dang really. Was hoping to make use of the bits of 2.5'' I had. What if I were to get some 2'' o,d pipe and just flare the end out 2.5'' like the factory cast one just that its pointing straight???
