EXHAUST PRE-SILENCER, 84-85 13B 6-PORT
The Racing Beat Power Pulse Presilencer for the 1984-85 RX-7 GSL-SE (13B 6-Port engine is designed to be used with our wide selection of RX-7 Streetable Headers to complete a bolt-on configuration. When used along with a Racing Beat header, this presilencer will connect the header to the connecting pipe section, offering a true bolt-on configuration. These Power Pulse Presilencers are also ideal for those individuals wanting to fabricate custom exhaust systems incorporating either long or short primary exhaust systems. This presilencer unit is equipped with an exhaust gas back-pressure pickup tube to allow for the correct operation of the 6-Port intake actuator valves.
The Power Pulse Presilencer improves the character of the exhaust noise, dramatically reducing the inherent, obnoxious metallic high frequency noise with virtually no power loss. Constructed with a high temperature, 2-inch I.D. perforated core of 304 stainless steel wrapped with high-temperature stainless steel wool, the Power Pulse Presilencer measures 20 inches in length with a 4-inch outside diameter. The mounting hanger (if provided) has been designed to mount this presilencer to the specific application listed above. The mounting studs are 10mm both front and rear.

EXHAUST SYSTEM SINGLE, 84-85 13B SE
Racing Beat Single Exhuast System, 84-85 13B SE
Racing Beat offers a complete RX-7 high-performance exhaust system for the 1984-85 13B (GSL-SE) RX-7. This system includes our Road Race Header, a Power-Pulse Presilencer, and our legendary Power Pulse main muffler. The Power Pulse Presilencer unit is equipped with an exhaust backpressure pickup tube that allows the correct operation of the 6-Port intake actuators. Be careful, if you are considering a replacement exhaust system that does not have this important feature, your intake system will not perform correctly and a noticeable decrease in high RPM performance will occur.
These components attach to all stock mounting points, and include all necessary gaskets and hardware. The only component not included is the factory connecting pipe that mounts just ahead of the main muffler. There is no horsepower to be gained by replacing this pipe with a larger diameter assembly. If your factory connecting pipe needs replacing, we suggest you contact your local muffler shop.
These exhaust systems offer excellent horsepower gains when you require a muffled exhaust system for your stock-ported engine. The actual horsepower increase depends on which year/model stock RX-7 exhaust system you are comparing to, but a 22% increase at 7000 rpm is typical. Thanks to the combined efforts of the Power-Pulse Presilencer and the Power Pulse Main muffler, the exhaust noise is only slightly higher than stock, with a very low, pleasant character.

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.
