Miata headers are a great way to add power and responsiveness to any Miata. 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).
Do NOT wrap headers. Wrapping headers VOIDS THE WARRANTY on every brand of header made. The wrap holds moisture and also gathers petroleum emissions from under the hood like any oil leaking (meaning eventually you can have a fire). Result includes fast degradation of that gorgeous polished stainless surface and the welds. Wrapping headers is something that came from Drag Racing, but the Pro Drag Racers know it kills the header in exchange for another 1 or 2 hp scavenging benefit and they accept that it also means they get to rebuild the headers at the end of every race season. Instead of wrapping headers consider our ceramic coated versions, or our header heat blankets (which don't trap moisture).
