1979-80 RX-7 Power Pulse Muffler
Racing Beat has been manufacturing replacement exhaust components for rotary powered vehicles for over 45 years. Ordinary replacement mufflers don't stand a chance against the extreme temperatures and pounding exhaust gas pulsations generated by the rotary engine. Many of these replacement mufflers will quickly burn up the packing material and self-destruct under these harsh conditions.
Our Power Pulse Main RX-7 Mufflers interchange exactly with the stock RX-7 muffler on the 1979-80 chassis years. Assembled in-house by Racing Beat, this muffler features a 304 stainless steel muffler canister, polished stainless dual tips, inlet & outlet pipes and hangers. In a typical application, this muffler adds up to 5 HP over the Mazda factory muffler with an improved note. Emissions legal, this muffler bolts to the outlet of the connecting pipe section.
Note: The Mazda OE ring gasket is no longer available from Mazda or our aftermarket supplier, hang on to the original gasket!
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.
