The difference is the 2.5" will spool faster and torque will come on strong due to the back pressure in the 2.5" exhaust. With the 3" you will see higher whp numbers and your tuner should be able to control the torque better which allows for the increase in top end. Spool not really a factor unless you are using a large turbo from what I can tell on our cars.
