I have a question on the bolts/nuts on the driver's side header-to-manifold. Mine has three bolts (I know the top one is a stud), but only has 2 nuts. The lower bolt is without a nut on the end. I think it's threaded into the cat? Or the bolt is missing.
Previous owner removed the cats, went to test pipes...then put the car back to stock. I'm just not sure if a bolt is missing or not. I'm thinking it's fine although the bolt is a little sideways in there.
Pictures here.
