Cadillac STS Posted October 24, 2004 Report Share Posted October 24, 2004 actually from the cat to the y-pipe its 2.5..in and out stock is 2 Doesnt matter if your going with 2.5 aftermarket mufflers because its actually better for the person/shop who instlalls it. Since they can just slip in above the old pipe and weld instead of beating the edges to get them to connect Link to comment Share on other sites More sharing options...
