Anyone know what size "nut" is on the Exhaust Manifold?

 

Go look and see, that's not to hard and by now you would have known.

 

Yeah I got it, I was outside playing with my kid when I looked to see that it was a star shaped bolt. I completely forgot I have a set of those in my impact set, never used them.

Sorry for the post, but I did not want to make a trip to the auto store if I did not know the correct size.

 

12mm 12 point socket, I did not have the right one. I thought it was a reverse Torx. Got the Manifold off and Advanced had the replacement 8 x 1.25mm studs in their help section, they are longer on the downside but work fine. Replaced all 3 and now just need to pull the intake for the tune-up.
