This exhaust gasket from Quad Logic is manufactured from a thick stainless steel mesh wrapped in an outer layer of graphite. It is designed to perform even better than the stock Polaris gasket. Exact replacement for your Magnum. Most Magnum's use TWO gaskets total: one between the short head pipe and main pipe and another between the main pipe and the muffler. Be sure to order 2 if replacing both. Sold each. Replaces Polaris 5243517. Fits the 2000-02 Magnum 325, 2003-06 Magnum 330, and 1999-03 Magnum 500 models.
