    摘要： A substantially leak free joint connecting conduits in an exhaust system of an engine. The joint connects a first exhaust conduit extending between a first distal end and a first join end, and a second exhaust conduit extending between a second distal end and a second join end. The joint comprises a substantially circular bead formed by a tip of the first join end curled radially outward and around until it contacts an outer surface of the first exhaust conduit. A mating surface formed in the second join end that defines an at least partially axially open seat flared radially outward from the second exhaust conduit. At least a portion of the seat shaped to substantially conform to at least ninety degrees of a circumference of an external surface of the substantially circular bead. The external surface of the bead directly contacts the seat of the mating surface such that the portion of the seat curves around a portion of the circumference of the bead.
