i believe the consensus is that 2.5" pipes will do fine up to around 500 hp.
if you've got 3" collectors on the headers you will either need to get a reducer to connect to the 2.5" x or run full 3" exhaust of put the reducer after the x and use any of the currently ava. cat back systems (B&B Bullets rock).
you may lose some low end torque due to the larger pipes but it will run better in the top end.
