Second have an ORY with stock manifolds will make the car a little louder. However if you get a set of long tubes there will be an auidible difference between an ORY and a catted Y. Most will say that you will get more rasp with an ORY, this depends on which catback you use. I have Pacesetter LT's, ORY and a Hooker catback and there is very little rasp. however when the cutout is open I can tell that there is a fair amount of rasp.
I have a ypipe on my car (came with it when i bought it), it has cats, but they are down low, not in the stock location, and they are on the ypipe, so i would think you can get an offroad y pipe for stock manifolds.
