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 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 silencer canister with regards to the opening in the rear bumper. We have positioned the silencer canister “under” the rear bumper in order to present a more integrated look. Unlike many aftermarket systems that use a simple universal silencer, the Racing Beat system utilizes a rotary engine designed silencer 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. 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 exhaust system.
We offer a complete replacement hanger kit for all models of 1986-92 RX-7’s. See here.
