Power Pulse PR-Extreme Muffler
1979-85 RX-7 Universal
In response to numerous requests from customers demanding a very low restriction“street capable” muffler, Racing Beat now offers the Universal Power Pulse PR-Extreme RX-7 Muffler with a 3" ID design to meet the performance demands of high-horsepower ported rotary engines. The Power Pulse PR-Extreme RX-7 Muffler is compatible with all 1979-85 RX-7 muffler rear mounting positions and retains the factory stock dual appearance.
The Racing Beat Universal Power Pulse PR-Extreme RX-7 Muffler is manufactured utilizing a stainless steel canister shell and durable heat and noise insulating materials, specifically chosen for their resistence to the higher operating termperatures of the rotary engine exhaust. The 3" inlet opening empties into a central noise-suppression central chamber, and then exits rearward through dual 2" OD outlet tubes. The polished stainless steel 2.75" OD outlet tips are positioned to match the stock bumper opening on the 79-85 RX-7 chassis.
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.
