Your stock y will not work without some serious modifications if at all. Even if you do fab up some kind of y from the stock y-pipe, i seriously doubt it would flow as well as a 3" y-pipe you should be buying. IMO, I'd rather spend a couple hundred on a ORY than a couple hundred modifying my stock y-pipe. You'll be glad you did.

You can use shorty headers with the stock y-pipe and cats. I THINK people who have went the shorty route have shown gains of 2-10rwhp depending on car. Hopefully some of them will chime in for you. You won't be able to use your stock y-pipe and cats with mid-length or longtube headers without serious modification to the y-pipe (assuming it could be done at all).
FWIW, I gained 15rwhp/13rwtq with FLP longtubes through the FLP cats when I had the stock cam. Probably could add 3-5rwhp and rwtq to that number if I had the ORP on the car.
