1986-92 RX-7 Non-turbo Street Exhaust System - The Racing Beat street-legal, Power Pulse cat-back RX-7 exhaust system is the perfect replacement for your vehicle - a durable assembly offering a real horsepower gain over your stock unit. This complete bolt-on system has been extremely popular with RX-7 owners over the years and remains a serious choice for the next generation of RX-7 enthusiasts. If you need to retain the emissions status of your RX-7 and keep the sound level to a tolerable level - look no further than this Racing Beat system!
Our RX-7 exhaust system consists of a Racing Beat Y-pipe and two 2-inch (OD) 304-stainless steel Power Pulse mufflers. The replacement Y-pipe is manufactured using 2.5-inch (OD) tubing, splitting off into a pair of 2-inch (OD) tubes feeding the left and right Power Pulse Muffler canisters. (This larger diameter 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. We've positioned the muffler canister "under" the rear bumper in order to present a more integrated look. Unlike many aftermarket systems that use a simple universal muffler, the Racing Beat 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 system. This bolt-on system uses the stock mounting points for ease of installation. Each system is supplied with all necessary mounting hardware and gaskets.
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 exhaust system. If needed, we offer a complete hanger replacement kit which includes ALL required hangers for your RX-7.
We offer individual 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.
