Right now I have a cat back but I want to finish up the rest of my exhaust. I want to go with long tubes and an ORY but I am not sure of everything I will need for the installation. I hear of people using O2 sensor extensions and sims, do I need either of these? What else do I need for a sucessful installation. Also, can I replace my Y-pipe now and than go with long tubes later? Or are the Y pipes different for long tubes and stock manifolds?

I haven't done this myself, but I believe you need either the sims or the extensions as your check engine light will come on without the sensors connected. Also the Y-pipe that would replace the stock one is not compatible with long tubes so it needs to be done together as a package.
I wish I could go with that off-road setup, but here in Canada, I have to be fully emissions legal with cats.
