Want an option to those oem leaky exhaust gaskets?...100% graphite RemFlex gaskets are your answer. These are designed to be crushed to 50% of its original size, this means that if you have bad mating surface these will fill in the gaps for a perfect seal. The guys in the shop have been using these for awhile now and we all really like them. i personally got sooo sick of the thin oem gaskets leaking and then having to put atv on them to try to seal it but then that eventually blows out....no more!! We just finished working with RemFlex to create gaskets for each joint of all N/A Subaru engines. These gaskets include: Engine>Header Single Port Engine>Header Dual Port Header> 1st Cat 1st Cat> 2nd Cat Mid Pipe>Axel Back WHY Graphite Gaskets? -Seals Warped flanges. Fills i gaps up to 1/16" -No Re-Torquing necessary -Wont burn out, good up to 3000 degrees WHERE to buy? http://www.grimmspeed.com/catalog/index.php?cPath=60_33_35_43 HOW much?
