  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.
