Power Pulse RX-7 Muffler
81-82 RX-7

1981-82 RX-7 Power Pulse Main 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 we discovered an exhaust system supplier deep in the heart of the Italian countryside that was willing to produce our mufflers for us. That was over 30 years ago and we've never looked back! In fact, we can't ever recall having a complaint wthl one of these mufflers, they just flat out work. Solid, strong and quiet, they hold up extremely well against the abuse of the harsh rotary exhaust.

This Power Pulse RX-7 muffler is a large diameter high-flow muffler designed for street-ported engines as well as the stock 1981-1982 RX-7 chassis. It consists of two 1.75-inch tubes that collect into one 2.375-inch tube. It is slightly louder than our other Power Pulse Mufflers. 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 RX-7 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 muffler canister and tip position in the bumper opening.
