I'm looking into doing some longtubes from pacesetter and what I can't figure out is what kind of y-pipe I want. i dont want to go true dual and my car has to pass emissions tests so I would like to keep the o2 sensors (front and back). Can I get an ORY and put cats after the long tubes then go through the y or do I have to get a catted Y or is that the same thing? Just confused.
