Exhaust flange stud removal

[hrforever]

I'm making a set of headers and would like to remove one or two of the flange studs from the head, hopefully without damaging or breaking them. Is there an easy way to do this? The end appears to be like a 'torx' fitting but is there an available socket to suit it? Are they a left or right hand thread? The motors in the car so space is at a premium.

There are sockets avaliable to fit onto the end of them. The normally come out quite easily. Cheers

two nuts tightened together, as said they come out easy.

Thanks. Will try using 'old' nuts.

Ebay has a lot of sockets for those torx studs. The 2 nuts method should work easily if the engine is outside.

Tried the two nut option today. Tried turning anti-clockwise but didn't work. Tried clock wise, same result. Nuts turned no matter how tight they were. Will have to investigate tools.

Hold ring spanner on both .. If anything longer spanner on inner and hold a little pre-load on outer nut while turning harder on inside ...
Make sure there's enough thread on BOTH nuts.

Finally got around to having another go. Two newer nuts worked a treat. Thanks for all the assistance.
