The Racing Beat street legal, Power Pulse cat-back RX-7 exhaust system is the perfect replacement for your RX-7 exhaust - a durable assembly offering a real horsepower gain over your stock unit. 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!
This RX-7 exhaust system consists of a Racing Beat Y-pipe and two 2.375"-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.
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 7.3 HP gain over the stock system (stock Turbo II). 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 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.
