90-97 Miata Racing Beat Power Pulse Muffler (56451)
Connecting Pipe (Required)
Each Power Pulse Muffler requires the use of a Racing Beat connecting pipe section.Designed and manufactured by Racing Beat, our Power Pulse Muffler is intended for use on all 1990-1997 Miatas. The heart of our Power Pulse Exhaust System is our polished 304-stainless steel muffler canister. This polished canister is equipped with stainless steel inlet and outlet pipes for superior durability. For maximum performance the Power Pulse Muffler features the same 2.375" OD Straight-Flow internal design configuration as our RX-7 Turbo II exhaust systems. The 3.5" OD exhaust tip is manufactured using highly polished 304-stainless steel and is slightly oval in shape to provide a perfect balance and proportional look for the Miata's rear bumper. Each tip features a etched Racing Beat logo to add the finishing touch!
90-97 Miata Racing Beat Power Pulse Muffler Sport Connecting Pipe (56435/56436)
Select your year below to receive the correct part.
For Miata owners that prefer a more aggressive sounding and lighter weight exhaust system, this Sport Connecting Pipe (without presilencer) can be used with either our single or dual outlet Power Pulse Muffler.
Many people ask just how much louder the Sport Pipe is as compared to the Power Pulse Connecting Pipe. For comparison purposes, we undertook a series of decibel readings to record the sound level outputs.93-95 Rx7 Racing Beat Dual Tip Muffler (16427)
Racing Beat RX-7 Dual Tip Exhaust System - Every Racing Beat 304-Series 1993-95 RX-7 Exhaust System benefits from high-quality materials and exacting construction techniques to provide superior performance and sound. The RX-7 FD3S exhaust system is designed by Racing Beat to maximize performance while maintaining a deep and mellow exhaust note. Normal driving produces a mellow deep tone, but jump on the throttle and these systems come alive with an even deeper, throaty sound.
79-80 Rx7 Racing Beat Power Pulse Muffler (16430)
Racing Beat has been manufacturing replacement muffler canisters for rotary powered vehicles for over 40 years. Ordinary replacement mufflers don't stand a chance against the extreme temperatures and pounding exhaust gas pulsation generated by the rotary engine. Many of these replacement mufflers will quickly burn up the packing material and self-destruct under these harsh conditions. Many years ago we discovered an exhaust system supplier deep in the heart of the Italian countryside that was willing to produce our RX-7 mufflers for us. That was over 30 years ago and we've never looked back! In fact, we can't ever recall having a complaint with one of these mufflers, they just flat out work. Solid, strong and quiet, they hold up extremely well against the abuse of the harsh rotary exhaust.
Our Power Pulse Main RX-7 Mufflers interchange exactly with the stock RX-7 muffler on the 1979-80 chassis years. The main body of the muffler 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 muffler with an improved note - deep and throaty, with no annoying metallic character. Emissions legal, this muffler bolts to the outlet of the connecting pipe section. Gaskets are not included, but are available separately if needed.
79-85 Rx7 Power Pulse PR-Extreme Universal Muffler (RB-16436)
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 2.75" OD internal perforated core 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 appearance; this PR-Extreme RX-7 Muffler includes an inlet pipe measuring, nominally, 6 inches in length x 2.75" OD.
The Racing Beat Universal Power Pulse PR-Extreme RX-7 Muffler is manufactured by the same exhaust components manufacturer that has produced our "tried and proven" First Generation RX-7 Power Pulse mufflers (1979-80, 1981-82, and 1984-85) since the mid-1980s. Utilizing a heavy-walled canister shell and extremely durable heat and noise insulating materials, the Racing Beat Power Pulse PR-Extreme RX-7 Muffler is engineered for the high exhaust gas temperatures found in rotary engine applications.
The main body of the muffler canister measures 8 inches in diameter and 18 inches in length. The dual outlet tips are completely chrome-plated with straight-cut outlet.
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.
