Hey guys I was wondering if anyone knew the exhaust manifold stud size. I pulled a couple out when I was replacing my manifold and I have a leak. I would like to try and find some like these from Mugen they have a hex head to install them. http://www.kingmotorsports.com...at=65

No one can verify the size or Is my idea just stupid?

If you got them off, why not use a thread/ pitch gauge to determine the thread and pitch. Go to ACE hardware or an auto parts store, they should be able to help. Unless someone on here has the quick answer.

I don't know that it's stupid, but I don't see that it's necessary. You can still order them new from Nissan (I just did).

10x 1.25. to reinstall them try putting two nuts on tight to each other and only turning the outer nut , should tighten the stud into the head plenty.

what you need is the locking nuts

do a search as it is a common problem and I seen someone posted up this particular product in the past

good luck
