Complete exhaust system RX-7 12A 1984-85
Product information "Complete exhaust system RX-7 12A 1984-85"
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 stainless steel Power-Pulse Presilencer, and our legendary stainless steel 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. If your factory connecting pipe needs replacing, the Racing Beat stainless connecting pipe is a direct replacement of the OEM unit.
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.
