EXHAUST SYSTEM SINGLE, 84-85 12A MANUAL
Racing Beat offers a complete RX-7 high-performance exhaust system for the 1984-85 12A RX-7 (w/manual 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 do offer it separately; the part number is 40-200C-N249.
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.

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.
