      Does anyone know what tool i need to take this nut of my exhaust manifold.  It looks like an allen key type nut tho has a steal rod running up the centre of it. Sorry photo not great.

      Wow!

      Sadly , I’ve seen this a few times over at the facebook group , usually you could try these tricks:

      • Drill the center of the bolt with a HSS bit, until the bolt-head splits
      • or get a hole saw drill bit that is HSS about 12-14mm size (A guess) and drill-saw the area surrounding the bolt.  Then the flange comes off by pulling it off with tools.
      • The bolt that is left attached on engine-header, get large mole grips & wear bike gloves , try to undo it hard to loose.

      Mind you, whatever happens here, you may end up replacing the stud & nut or a new exhaust bolt!

       

      That picture ^ that bolt is a security torx bit. It is size T30-Security Torx.   very notorious bolt to fight with sometimes.
