On the front half of the manifold, on the top side, is a raised cylindrical area, about 3/8" diameter with a dimple in it. This is where you drill and tap.Where is the best place to drill and tap for the EGT probe on the ATS exhaust manifold?
I could only find one picture that shows it here:will look again, but I did not see the are you are talking about in this manifold. Could you possibly post a picture please?
