Other than the O2 ports for pipes 07 and up is there any difference from them and the 06 previous? If not how do I bypass the o2 Sensors?
The older fuel systems were open-loop and did not use 02 sensors. The Delphi system is closed-loop and needs the 02 sensors for more precise fuel control to meet emissions. I don't know if there is any differance in the pipes but don't mess with the sensors, you need them for the engine to run right.
If you add pipes and an air cleaner then you will need a fuel controler to help it run the best it can.
