We all agree that our y-pipe is a major restriction for us. I know that JBA, Magnaflow, make y-pipe kits is there any others?

I know that Pacesetter has some too but they are all 3". Too much fabbing to the stockers.

Anyone have any other options and or possible HP gains on switching?

Conecting the 3 inch part to the existing 2.75 stock pipe, for a muffler company, would not be hard at all. Not sure about connecting the two pipe from either bank to the y pipe. Im sure they can do it no problem, might not look pretty though.
