exhaust/gearbox bolt keeps coming loose

  1. #1
    the bolt that is on the bottom of the downpipe where it bolts on to the gearbox keeps coming loose, its a star nut bolt (t50) and its a mk2 vtr 2001. Everytime i do it up it keeps coming loose so all you can here is a horrible rattle everywere u go. Any sudgestion son solving this other than trying lock thread?
