1986-92 Non-turbo Street Exhaust System.

This street legal, cat-back exhaust system is the perfect replacement for your RX-7 - a durable assembly offering a real horsepower gain for your stock unit.

Our RX7 exhaust system consists of a Racing Beat Y-pipe and two 2-inch (OD) 304-stainless steel Power Pulse muffler canisters. The replacement Y-pipe is manufactured using 2.5-inch (OD) tubing, splitting off into a pair of 2-inch (OD) tubes feeding the muffler canisters. (This Y-pipe can be used as a direct replacement for the factory Y- pipe.) Both muffler canisters are finished with a 3-inch, polished 304 stainless tips for an aggressive look.

Careful consideration was given to the correct placement of each muffler canister with regards to the opening in the rear bumper. The muffler canister was placed under the rear bumper in order to present a more integrated look.

Unlike many aftermarket RX7 exhaust systems that use a simple universal muffler, the Racing Beat RX7 exhaust system utilizes a rotary engine designed muffler that has been specifically designed for the 1986-92 RX-7 application. Performance tests on a Dyno Jet chassis dyno have shown a 5-7 HP gain over the stock RX7 Exhaust.

This bolt-on RX7 Exhaust uses the stock mounting points for ease of installation. Each RX7 exhaust is supplied with all necessary mounting hardware and gaskets. These components are also available separately.

Replacement Rubber Exhaust Hangers We recommend the replacement of the original rubber exhaust hangers during the installation of any new exhaust component. It is our experience that over time the original rubber hangers can deteriorate, crack, and fail; which can result in the incorrect alignment of the RX7 exhaust system. We offer replacement exhaust hangers for all models of 1986-92 RX-7 s. Review the Exhaust Hanger Chart for details on the exact components that are required for your exhaust system.

Good morning Brian, I finally got a chance to put the exhaust on, great advice, it's just loud enough, solid product. I'm running without the baffles, sounds great in power band. Take care, you have all my future upgrade business.........regards.

I received the Roadstersport II, and I wanted to compliment you guys on an awesome product. The Miata should have these on from the factory. They make a great sound, that is not obnoxious at all. The exhaust also installed seamlessly!!! I will buy all of my Miata stuff from you in the future. Thanks,
