EXHAUST SYSTEM DUAL, 13B DUAL PIPE 79-85

Our Racing Beat-designed, “Long Primary” Street Port Complete RX-7 Exhaust System is designed for any 1979-85 RX-7 with a 13B street-ported engine. Designed specifically to optimize the performance benefit of a ported rotary engine, this RX-7 exhaust system will provide the maximum power output possible from an aftermarket RX-7 exhaust system. While louder than the stock system, the dual resonated center section offers maximum exhaust gas flow and scavenging while reducing sound output to a modest level.

Offered as a packaged set, this kit consists of a Road Race Header, the Street Port Center Section, and a high flow Power Pulse Main muffler.

The Long Primary system typically adds 5% or more horsepower over a standard Short Primary system on a street ported engine, especially at higher RPMs. This system can also be used on non-ported engines with good results. It is strictly bolt-on, with no welding required. These complete “bolt-on” systems come complete with all required mounting hardware and gaskets. Since this is intended for racing applications, there is no provision for an oxygen sensor on this system.

    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.
