You wont get any gains by going to a 3" system unles that is what is the limiting factor in your setup (do you have 400bhp)??

Ported oem Headers and matching up pipe should see you spool up a little eariler and also add a few ftlb's with a remap.

with matching or near torque readings.

mine's managed 340 bhp with a 2.5/3 system from TSL, but 3" is needed around the 400 bhp mark

IMHO
