I guess we should also note here for the inexperienced that the quality of the bends and general layout of the piping also changes everything. If you have good mandrel bends and a relatively straight path, 2.5" is plenty for all NA I6's. But if you're crush bending and have a compromised setup, I'd go 2.75" on a 3.0/3.2.
