good cats will only hold a single digit difference compared to its o/r couterpart. i personally think the sould is a little cleaner as well with cats depending on pid pipe and choice of cat back.

hp difference will be minimal, o/r will be a little louder, catted will cost you a whole lot more.

I'm convinced that its the o/r mid-pipe that give you the most horsepower gain. A new catted mid-pipe still has the restriction in it.
