EXHAUST HEADER 12A, 84-85 RX7 (MANUAL TRANSMISSION)
Racing Beat 12A Exhaust Header, 84-85 RX7 with Manual Transmission
Actual header not shown in photo – oxygen sensor fitting only included on 1984-85 RX-7 GSL-SE header.
The Racing Beat RX-7 Header is designed for a bolt-on installation, when used with the appropriate Power Pulse Presilencer in all 1984-85 RX-7s (12A – Manual Transmission). The combination of this RX-7 exhaust header and the appropriate presilencer replaces the stock exhaust manifold and all catalytic converters for use in racing applications, along with any intermediate pieces of tubing.
This RX-7 header assembly is constructed with .120-inch wall, mandrel-bend, mild steel tubing for increased durability. The engine-to-header flange is laser-cut from .5-inch thick steel plate to ensure positive gas sealing. An outlet gasket is included. An engine-to-header gasket is available separately if needed.
