Racing Beat's Road Racing Header for the 1984-92 RX-7 13B (6-Port) is the first step in building a serious racing exhaust system. The engine-to-pipe flange is laser cut from 1/5" thick flat steel. Like all of the headers we manufacture, the Road Racing Header is constructed with 2" OD mild steel tubing, .120" inch wall thickness, and mandrel-bent tubing throughout.
Outlet flange gaskets, bolts, and nuts are included. If needed, an engine-to-header gasket is available separately. An Air Control and Check Valve Cover Plate is required when using this header with a stock intake system. The Road Race Header can also be used as the basis for a custom streetable exhaust system in any car from 1971-92 (equipped with a 6-port engine), which allows simple swapping between street and race exhaust systems.
This header can used with the Street Port Center-Section Pipe 1979-85 12A & 13B except GSL-SE or 1984-85 GSL-SE.
