Flatout Gaskets Header Gaskets

4.6 out of 5 stars 10 Customer Reviews

Flatout offers a comprehensive line of performance gaskets, including header gaskets, which are engineered from top-grade materials to take on high-heat produced by your exhaust headers. Their high thermal conductivity pulls heat away from the heat source and allows them to expand and contract without damage. Flatout header gaskets feature smooth contours, accurate hole locations, and tight tolerances to provide an exceptional fit and seal. Get the most performance out of your engine, use Flatout header gaskets--they seal where others don't!
