Miata headers are a great way to add power and responsiveness to any Miata. Our Miata headers come in two brands: Racing Beat and Jackson Racing. Each Miata header sold here includes the downstream gasket needed for installation (and the gasket for connection to the engine is re-useable stainless steel that does NOT need to be replaced to install a new Miata header). Racing Beat Miata headers feature polished 304 stainless steel four-into-one designs for maximum power. The Racing Beat Miata header is not CARB approved for those enthusiasts subject to California smog rules, does not fit with automatic transmissions, and does not fit with some exhaust side Miata superchargers. Our Jackson Racing Miata header features a 4-2-1 design that is ceramic coated heavy gauge steel and CARB approved, fits will all our supercharger choices, but does not fit with automatic transmissions.

For maximum Miata header flow, consider updating your downstream Miata catalytic converter if it is old, and your Miata exhaust if original.
