An exhaust manifold gasket for sealing between an exhaust header and a first mating flange includes a metal layer having at least two integral tabs formed on an outer periphery of the metal layer. The first mating flange further includes at least two apertures located within the first outer periphery that are correspondingly sized and positioned to receive the tabs. In one embodiment each tab comprises two contoured, resilient legs separated to form a vertical slot between the legs, and a contoured tip located at a distal end of each tab leg. The contoured tip includes a sloped portion that slopes laterally outwardly from the distal end of each tab leg along an outside edge of each tab leg and terminates in a laterally outwardly extending protrusion for providing a tight interference fit when inserted into a corresponding aperture. In another embodiment, each tab includes a serrated resilient edge that promotes tab insertion, but digs into an inner periphery of the aperture upon attempted tab removal.
