Had an awful metal rattling sound on my 78 that turned out to be the collar coming up from the pipe to the bottom of the manifold. I guess my question is whether or not this piece is critical to seal or if a new donut will be enough...If it needs to be there, can any exhaust/muffler place fix it?

Are you talking about no 4 in the pic?

No, that is for an eariler year with a 2 bolt flange

But it is the same functionality and SOR does not have any.
