How did you get the 4" pipe to mate with the Y-pipe? Did you use an adapter or what?

I had the Y-collector cut back just a bit until it was about 3". Then, I had aluminumized pipe ran back into a DynoMax race bullet muffler.

Old thread revive I know, but I am thinking of doing the same thing, except having a y pipe after the muffler and going to 2.5" duals. Ant issues with this???
