EXHAUST SYSTEM DUAL, 84-85 13B 6 PORT
Racing Beat Dual Exhaust System, 84-85 13B 6 Port (using a carburetor)
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 (for a 13B 6-Port engine), 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. The center section for this application includes an exhaust backpressure pickup for to allow the correct operation of the 6-Port intake actuators. Since this is intended for racing applications, there is no provision for an oxygen sensor on this system.

MUFFLER POWER PULSE, 83-85 ALL RACING BEAT
Racing Beat Power Pulse Muffler, 83-85 All
1983-85 RX-7 Power Pulse Muffler – Racing Beat has been manufacturing replacement muffler canisters for rotary powered vehicles for over 40 years. Ordinary replacement mufflers don’t stand a chance against the extreme temperatures and pounding exhaust gas pulsation generated by the rotary engine. Many of these replacement RX-7 mufflers will quickly burn up the packing material and self-destruct under these harsh conditions. Many years ago Racing Beat discovered an exhaust system supplier deep in the heart of the Italian countryside that was willing to produce Their RX-7 mufflers for them. That was over 30 years ago and they have never looked back! In fact, we can’t ever recall having a complaint with one of their mufflers, they just flat out work. Solid, strong and quiet, they hold up extremely well against the abuse of the harsh rotary exhaust.
The Power Pulse RX-7 Mufflers interchange exactly with the stock RX-7 muffler on the 1983-85 chassis years. The main body of the muffler measures 8 inches in diameter and 18 inches in length. The heavy-duty construction, both internally and externally, ensures a long life. In a typical application, this muffler adds up to 5 HP over the Mazda factory muffler and is as quiet as a stock muffler with an improved note – deep and throaty, with no annoying metallic character. Emissions legal, this muffler bolts to the outlet of the connecting pipe section. Gaskets are not included, but are available separately if needed.
Now may be the time to consider replacing the old rubber muffler hangers on your RX-7. New replacement hangers will ensure correct alignment of the RX-7 muffler canister and tip position in the bumper opening.
