Y Pipe
#2
While I don't have a used Y-pipe for sale, there are many options into having one made for a great price at an exhaust shop. There are a couple universal ones on ebay made by Flowmaster that have a pretty smooth merge into 3" from 2.25" and 2.5"

You should buy to 45 degree mandrel bends. Split those down the middle and weld both halves together making a Y. I've made a couple that way and they work great. Costs about $50 to make a nice 3" stainless Y.
You can kind of see what I'm talking about in this picture.
