Thank you. You have rated this product.

Racing Beat has been manufacturing replacement muffler canisters for rotary powered vehicles for over 25 years. Ordinary replacement mufflers do not 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.

This muffler is a large diameter high-flow muffler 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 Mufflers.

This Power Pulse Main Muffler assembly interchanges exactly with the stock RX-7 muffler on the 1981-82 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. Gaskets are not included, but are available separately.

I got the oil cooler installed and I'm diggin' it! Thanks. (product # 10-10012)

After reading many other positive reviews on both the GWR and Miata forums I finally decided to buy this product. My main concern for many months was whether or not I was up to the task of installing the header. But with the excellent instructions on Brian's forum as well as several Miata forum threads it turned out easier than I expected. After receiving notice that the header would arrive on a Friday afternoon, I began the disassembly process. After about 3 hours I had the stock manifold out. Later that afternoon the new catted header arrived right on schedule. And it is a thing of beauty. I opted for the stainless version. Installation on Saturday morning took another 3 hours, although I could have shaved some time off of that but I was actually enjoying the process of double checking torque values and cleaning up my engine compartment. I already have the GWR catted midpipe, so that connection was a snap. I put everything back together, reconnected my battery, and went for a drive. NO CODES! Nice throaty sound with my RSII muffler, and a significant boost in power and low/mid torque. Another happy camper here. I since have added a M-E tune and I feel I have realized all of the gains that Brian has achieved on his 2012 project Miata. I've put several hundred miles on my Miata since the install with zero problems. This is the car that Mazda should have built all along. Thanks Brian.
