pretty sure its 2.25..not much power to be gained ( if any at all) from going up to 2.5" piping. I replaced my stock middle muffler/resonator with a 2.25" straight pipe and the stock rear muffler with a high flow magnaflow and I felt a little increase in power.

From my experience 2.25 only becomes and issue around 200hp.
