What is better stock on the car is two out to y pipe than to one muffler and on pipe? I was looking at the toastmaster 50 delta they have a 2 in 2 out would that be better or true dual? Also, I have new piping it comes with a x pipe would that be okay to use with a 2in 2out? Pipe size 2.25.

I have always felt a true dual exhaust was better because it allowed for better engine breathing.
Think about it this way by taking it to extremes. Nascar race cars do not have mufflers because they would create a restriction to engine breathing and you would not want that because you would want as much engine breathing as possible.
On the other hand, think how an engine would run with a potato stuffed into the tailpipe. The engine would stall. Because it has just cut off all the possibility of engine breathing.
