Yes. But.

3 inch is not necessary unless there is a need to evacuate greater volume of exhaust gasses. A larger turbo with associated intake and fueling mods would benefit from large diameter tubing.

If you never plan on installing a larger turbo, go for the 2.5 inch. Hybrid turbo options are likely fine with 2.5 as well.

A caveat, I have 3 inch exhaust installed (Thermal R&D from Mr. Ron Whoosh), and have not bothered with any warranty voiding large turbo, yet.. though... Whoosh does have quite a selection...
