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.
