Abstract: A substantially squeak-free heat cured exhaust seal adapted to be interposed between a pair of confronting pipes in sealing relationship therewith, comprises a one-piece substantially rigid grommet and a heat cured seal body of annular configuration and flat radial surfaces of different area at either end. The seal body comprises a mixture of metallic fibers, non-metallic filler, a thermally stable lubricant and a resin binder, and the grommet covers the entire inner circumference of the seal body, at least partially the large flat radial surface at one end of the seal body, and optionally at least partially the small flat radial surface of the seal body at the other end thereof.
