The Power Pulse PR-Extreme RX-7 Muffler is compatible with all 1979-85 RX-7 muffler rear mounting positions and retains the factory stock appearance; this PR-Extreme RX-7 Muffler includes an inlet of 3″.
The Racing Beat Universal Power Pulse PR-Extreme RX-7 Muffler is manufactured by the same exhaust components manufacturer that has produced the “tried and proven” First Generation RX-7 Power Pulse mufflers (1979-80, 1981-82, and 1984-85) since the mid-1980s. Utilizing a heavy-walled canister shell and extremely durable heat and noise insulating materials, the Racing Beat Power Pulse PR-Extreme RX-7 Muffler is engineered for the high exhaust gas temperatures found in rotary engine applications.
The main body of the muffler canister measures 8 inches in diameter and 18 inches in length. The dual outlet tips are completely chrome-plated with straight-cut outlet.

EXHAUST SYSTEM SINGLE, 84-85 12A AUTOMATIC TRANSMISSION
Racing Beat Single Exhaust System, 84-85 12A with Automatic Transmission
Racing Beat offers a complete RX-7 high-performance exhaust system for the 1984-85 12A RX-7 (w/automatic transmission) which includes our Header/Collector, a Power-Pulse Presilencer, and our legendary Power Pulse main muffler. 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 Mazda dealer or 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.
