I remounted the heat shields the way they are suppose to be,and where the notched out part is where the Y pipe used to meet I bought a 4in straight,for a 2 1/4in pipe,centered it up and placed over the Y opening...kind of gives it a staggered look but I like it a lot better than what Fullsac suggest.I also used the Kuryakyn "bridge the gap" piece to fill in the gap by the floor board...
