    EXHAUST HEADER 13B, 86-92 RX7 NON-TURBO

    Racing Beat 13B 6 Port Exhaust Header, 86-92 RX7 Non-Turbo

    Racing Beat’s rotary exhaust Header/Collector 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/Collector 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.)

    The Header/Collector assembly is constructed with .120″ wall, mandrel-bent, mild steel tubing (2″ OD primary, 2.5″ OD secondary) for excellent durability and noise suppression. Both flanges are laser cut from 7/16″ thick steel plate for positive gas sealing. An outlet gasket is included. An engine-to-header gasket is available separately if needed. This header is equipped with an oxygen sensor fitting.

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.

  • EXHAUST HEADER 13B, 74-78 NO FLANGE EX PICK UP

    EXHAUST HEADER 13B, 74-78 NO FLANGE EXCEPT PICK UP

    Racing Beat 13B Exhaust Header, 74-78 No Flange. Will not work on the Pick Up

    This rotary exhaust Header/Collector (less outlet flange) is ideal for RX-2, RX-3, RX-4, and COSMO (does not fit rotary pickup) custom exhaust installations. The flame-cut, .5-inch thick engine flange provides positive sealing and alignment. By integrating the collector with the header we reduce the effort and cost in completing the exhaust system. Engine-to-pipe gaskets are not included but are available separately. An Air Control and Check Valve Cover Plate is required when using this header with a stock intake system. 

    If the stock resonator is eliminated during installation of this unit, we strongly recommend selecting a Power Pulse Presilencer and installing it in place of the resonator to maintain a pleasant noise level and character.

  • Exhaust Down Pipe 86-92 Non-Turbo Coupes 2 1/2"

    Exhaust Down Pipe for 86-92 RX7 Non-Turbo Coupe 2 1/2″

    Exhaust Down Pipe 86-92 Non-Turbo Coupes 2 1/2″

    This Down Pipe is available for custom applications in a 1986-91 RX-7 (excluding convertible) non-turbo application. This 2.5-inch down pipe fits either manual or automatic transmission equipped cars and eliminates the catalytic converter sections.

    This down pipe bolts to the stock exhaust manifold, but the use of our presilencer (or a suitable replacement) is required to connect this assembly to the Y-pipe section. If you need to retain a catalytic converter in your exhaust system, you may find a suitable unit offered in the aftermarket. Although the replacement of your stock catalytic converters with a single aftermarket unit is technically NOT legal, this approach may suit your emissions needs. We suggest you contact your local emissions testing facility for more information. Gaskets sold separately.
