1998 mustang v6 converting to dual exhaust

I have a manual 1998 v6 and I'm going to convert it to a dual exhaust. Does anyone know if this will hurt the performance of the engine, hurt gas mileage, possibly damage the engine, and any other possible issues. I'm putting a catted x-mid pipe thats 2.5" in diameter that's made by pypes. The catback I'm putting on is the flowmaster american thunder with super 44 series mufflers. Any information will be great.

Correct: 2.25" (or 2-1/4").

The V6 does not "require" any cross pipe, since it is even firing. Therefore, H-pipe (better sound?), X-pipe (faster flow?), or divorced/split are all options. Getting rid of the stock Y will net the most hp. :bigthumbsup
