ok guys, my buddy just called me and needs a little help. He just installed LG Pro long tubes, x-pipe, and Borla stinger cat back. He bought everything used and called me to see if I can find out from you guys what size bolt is used to bolt the long tubes up to the bell housing (looks like the a bell housing from what I can tell). The stock system was not bolted there but the new has brackets welded on it. Here is a pic he sent me (circled the bracket)
