I just finished getting this installed this evening and wanted to share this with others who are going to be installing the kit. When you open the box, it is going to come with A LOT of extra stuff (clamps, couplers, brackets, etc.) that you don’t need. What you will need is: 2 x tapered couplers (stock piping to ARM), 2 x long couplers (IC to pipe), 2 x 71/63 clamps for the stock pipes, 6 x 77/69 clamps for the IC and pipes, and the brackets you need are the two black ones that are in a bag along with two long bolts and nuts. Unless I am missing something, everything else can be ignored.
