A Reusable Exhaust Header Collector Gasket That Resists Leaks and Blowout Failures

Exhaust header collector gaskets have a tough job. They need to keep your engine’s hot exhaust gasses inside the header as the exhaust passes from the header on through the exhaust system. The header collector flange is not only a high heat source area, but one that sees a lot of stress and flex from engine vibrations and chassis flex. So, the exhaust header collector gasket needs to be up to the task to keep those hot gasses inside where they belong. Most headers ship with one time use paper exhaust header collector gaskets (or sometimes none at all!) that do not do a particularly good job of sealing unless the header collector flanges are perfect (and they rarely are). Tricks like soaking the paper gaskets in water or adding globs of silicone gasket maker all around the flange are just band-aids. Whether you’re installing brand new headers, or you’re looking for a quality header to exhaust pipe gasket to service a leak at your existing header collectors, our EXtreme triple layer collector gaskets are a great solution.

Three Layers of High Heat Resistant Material Provides Lasting Protection

Our EXtreme header collector gaskets feature two layers of perforated stainless steel gasket material sandwiching an inner core of high-temperature rubber-based gasket material, making for a long lasting exhaust header collector gasket that can be reused multiple times while sealing minor imperfections and surface irregularities. This allows header or exhaust system removal without having to worry about spending time scraping dried and burnt paper gasket material off your header collectors and/or exhaust pipe flanges. Once you’re ready to bolt your headers or exhaust back up, simply wipe down the exhaust header collector gasket surfaces and slip them in place between the exhaust pipes and your headers and torque your header collector bolts to spec. The .085-inch thick header flange gaskets remain pliable heat cycle after heat cycle to resist exhaust leaks and blow outs.

Available For Most Popular 3-Bolt Exhaust Header Collector Flanges

The application for this part number is the 3-bolt collector flange with 3-inch inside diameter flange specification and sold in pairs. If you’re in need of different diameter 3-bolt header flange gaskets, or you’re looking for a different application, including lake pipe style header gaskets, we offer our EXtreme header collector gaskets in many popular sizes. We also offer matching EXtreme header gaskets for such applications as SBC, BBC, SBF, and others to ensure your header seals properly both at the cylinder heads and at the collectors on your headers. Speedway Motors EXtreme header collector gaskets are some of the best header collector gaskets for the money.
