    81-85 13B Rx7 4-Port Racing Beat Streetable Header (16011)

    Racing Beat doesn't offer this anymore, Use RB-16130 Header instead.

     For use with an engine built with 12A cast irons and 84-85 13B GSL-SE rotor housings.

    This Streetable RX-7 Header is designed for a bolt-on installation, when used with the appropriate Power Pulse Presilencer in all 1981-85 RX-7s with 4-port intakes (excludes 1984-85 GSL-SE). The combination of this RX-7 exhaust header and the appropriate presilencer replaces the stock exhaust manifold and all catalytic converters, along with any intermediate pieces of tubing.

    The Racing Beat RX-7 header assembly is constructed with .120-inch wall, mandrel-bend, mild steel tubing for increased durability. Both flanges are flame-cut from .5-inch thick steel plate for positive gas sealing. An outlet gasket is included. An engine-to-header gasket is available separately if needed.
