Exhaust header nuts

[Felix]

Hi guys,

Currently in the process of taking my exhaust off and it has some really odd shaped nuts on the header bolts...Like almost star bits I hope some of you know what I'm on about, Do any of you know the dimenions and the correct socket bit to use to take these off without rounding off the nut?

Thank you

According to the attached its a 10mm socket.

Use a 12 point socket not the hex type for better fit

They're double hex 10mm nuts, so you need a double hex socket, or the loop end of a spanner will do.
