If you're like us and you run a header, chances are you've blown a header collector gasket and had to replace the thing. This is because the gaskets from header manufacturer are paper based. On top of that, some Thorley look-alike headers on the market use thin gauge steel for the collector flange which can warp and allow leakage.
Forget that! This one is made from a thick flexible aluminum. It won't burn out on you after so many thousand miles. Use it, reuse it, reuse it again.... this thing will last and last and last. Better than the Energizer Bunny! Comes with nice new shiny bolts too.
