Racing Beat RX-7 Exhaust Header 1986-92 RX-7 13B 6-Port Engine

Our rotary exhaust collected header is designed for a bolt-on installation, when used with the appropriate Power Pulse Presilencer, in all 1986-92 non-turbo RX-7s. The combination of this header and the appropriate presilencer replaces the stock exhaust manifold and all catalytic converters, along with any intermediate pieces of tubing. (In this application, the presilencer will bolt-up to the factory Y-pipe.)

For optimum performance gains for this application, we recommend that a header be used on an engine configured with a carburetor intake system. For this reason, we suggest another suitable configuration for use on a fuel-injected engine is the Racing Beat Catalytic Converter Replacement Pipe with Presilencer combo. These components offer comparable performance gains, quieter performance and a price advantage as compared with the header/presilencer combination. These components replace only the stock exhaust components located between the stock exhaust manifold and the Y-pipe.

The Racing Beat header is constructed with thick.120" wall, mandrel-bent, mild steel tubing (2" OD primary, 2.5" OD secondary) for excellent durability and noise suppression. Our engine-to-header flange (1/2" thick) and outlet flange (3/8"thick) are produced using hot-rolled steel and laser cut to ensure accurate alignment on our welding jigs and correct fitment once installed on your vehicle.

Included hardware:
Outlet gasket and mounting hardware
Air Control and Check Valve Cover Plate
Oxygen Sensor Extension Wire
Oxygen Sensor Fitting mounted to the header
