There are a few gaskets for the Superformance header collector, but we collaborated with the manufacturing facility to create a better, stronger, longer lasting trouble free gasket than ever before!

This new header collector gasket designed just for most Cobra header to side pipe collector flanges is thinner, more dense and does not cause the collector flanges to distort under compression! It solves all the concerns of previous gaskets and incorporates the ultra sealing qualities of the 100% flexible graphite material that reduces center flange burnout up to 3,000 degrees.

Much better sealing than even the custom made factory or aftermarket gaskets
. - Fits many other brands, too!

Always use new Bolts & Nuts for every gasket change!
Our hand selected Premium Hardware Kit includes 16 Grade-8 bolts that won't stretch and loosen. The unique fine thread provide superior clamping power. The kit also includes 16 Grade-8 mechanical locking nuts that will not loosen and are completely unaffected by heat. Never have to re-tighten flange bolts again!

MEASUREMENTS

These special gaskets likely fit other brand manufacturers and other applications not yet listed. So we included a diagram for you ro compare your own used  gaskets to. Sometimes the comparisons are not exactly perfect, but this allows you to decide whether they will work for your specific application.

Notice the burned out edges of this popular aftermarket gasket modeled after the original equipment being removed after only a few hundred miles of usage when it began to create an exhaust leak.

Our hand selected Premium Hardware Kit includes 16 Grade-8 bolts that won't stretch and loosen. The unique fine thread provide superior clamping power. The kit also includes 16 Grade-8 mechanical locking nuts that will not loosen and are completely unaffected by heat. Never have to re-tighten flange bolts again!

We have standard bolt and nut kits as well as custom hardware kits for thicker flanges, angled collector spacers and thick flat collector spacers. Just send us your measurements and we can put it together.
