1983-85 RX-7 Power Pulse Muffler
Racing Beat has been manufacturing replacement mufflers for rotary-powered vehicles for over 45 years! Ordinary replacement mufflers don't stand a chance against the extreme temperatures and pounding exhaust gas pulsation generated by the rotary engine and many replacement RX-7 mufflers will quickly burn up standard packing material and self-destruct under these harsh conditions.
The Racing Beat Power Pulse RX-7 muffler is a large diameter high-flow muffler designed for stock and "street-ported" engines in the 1983-1985 RX-7 chassis. Designed and manufactured by Racing Beat, our RX-7 Power Pulse muffler features a large diameter inlet tube that feeds into a high capacity stainless steel muffler canister. Dual outlet tubes directly exhaust gases through twin polished stainless steel muffler tips. Each muffler has been configured with self-aligning muffler hangers, however, we strongly recommend the use of new replacement hangers when installing a replacement muffler on any older chassis.
The use use of stainless steel materials, combined with heavy-duty construction, both internally and externally, ensures a long life for your upgraded muffler. In a typical application, our Power Pulse muffler adds up to 5 HP over the Mazda RX-7 factory muffler while providing an improved exhaust note - deep and throaty, with no annoying metallic character. Fully emissions legal, this muffler bolts to the outlet of the Mazda stock connecting pipe.
A replacement gasket is not included, but is available separately if needed.
