1981-82 RX-7 Power Pulse Main Silencer
Racing Beat has been manufacturing replacement silencer canisters for rotary powered vehicles for over 25 years. Ordinary replacement silencer don’t stand a chance against the extreme temperatures and pounding exhaust gas pulsation generated by the rotary engine. Many of these replacement silencer will quickly burn up the packing material and self-destruct under these harsh conditions.
This silencer is a large diameter high-flow silencer 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 silencers.
This Power Pulse Main Silencer assembly interchanges exactly with the stock RX-7 muffler on the 1981-82 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. Gaskets are not included, but are available separately.
