If you sell the oem pipes and put the money you were going to spend on PC on top you are more than halfway to brand new 2.5" pipes. If you get lucky a used set will pop up for ~500, or if you get really lucky you'll get both inlet and IC pipes brand new from ASH for 750 shipped like me :) It was supposed to be a "scratch and dent" sale but he PC'd the inlet pipes for me to match the IC pipes so they looked brand new and the only damage on the IC pipes was a slightly bent PCV nipple. Honestly they could have been sold to me as new and I wouldn't have had any complaints.
