1979-80 RX-7 Power Pulse Main silencer
Racing Beat has been manufacturing replacement silencer canisters for rotary powered vehicles for over 25 years. Ordinary replacement silencers don’t stand a chance against the extreme temperatures and pounding exhaust gas pulsation generated by the rotary engine. Many of these replacement silencers will quickly burn up the packing material and self-destruct under these harsh conditions.
Our Power Pulse Main silencers assemblies interchange exactly with the stock RX-7 muffler on the 1979-80 chassis years.
The main body of the silencer 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 silencer with an improved note - deep and throaty, with no annoying metallic character. Gaskets are not included, but are available separately.
