Free flow dual exhaust, do I need another tune?

Thinking about replacing the stock exhaust. If I go with a freer flowing dual exhaust do I need to get my Gryphon retuned? I've got an '05 Expy EB 5.4L. Everything else is stock except for Gott's mod and K&N air filter.

Nope.

By the way, I have every doubt in the world that you will actually find a "freer flowing" dual exhaust (especially a "true-dual") than an appropriately-sized single.
