Click to view attachmentThis is a Bursch style 911 exhaust/muffler assembly. It is the earlier dual inlet unit that is a direct fit on all 1965-73 911's. Will also work with later 911 year models as well that have the back dated early style heat exhangers as well. Can be used on 914/6 conversion cars as well. $175.
