EXHAUST PRE-SILENCER, 89-92 NON TURBO AUTO TRANS

The Racing Beat Power Pulse Presilencer for the 1989-92 RX-7 Non-turbo (w/ auto transmission) is designed to be used with our wide selection of RX-7 headers to complete a bolt-on configuration to the Y-pipe section. (Includes both coupe and convertible models.)

This same Power Pulse Presilencer is included as a sub-component with the Catalytic Converter Replacement Pipe/Presilencer assemblies we offer for all 1989-92 RX-7s. Furthermore, these Power Pulse Presilencers are ideal for those individuals wanting to fabricate custom exhaust systems incorporating either long or short primaries.

The Racing Beat Power Pulse Presilencer improves the character of the exhaust noise, dramatically reducing the inherent, obnoxious metallic high frequency noise with virtually no power loss. Constructed using a stainless-steel shell, interior core tube, and high temperature stainless packing wool, the Power Pulse Presilencer features a 2.5″ ID core and measures 20-inches in length with a 4-inch outside diameter. Each end is fitted with 12mm studs. The attachment hanger shown will allow correct fitment onto the exact application listed.

    Exhaust Down Pipe 86-92 Non-Turbo Coupes 2 1/2″

    Exhaust Down Pipe 86-92 Non-Turbo Coupes 2 1/2″

    This Down Pipe is available for custom applications in a 1986-91 RX-7 (excluding convertible) non-turbo application. This 2.5-inch down pipe fits either manual or automatic transmission equipped cars and eliminates the catalytic converter sections.

    This down pipe bolts to the stock exhaust manifold, but the use of our presilencer (or a suitable replacement) is required to connect this assembly to the Y-pipe section. If you need to retain a catalytic converter in your exhaust system, you may find a suitable unit offered in the aftermarket. Although the replacement of your stock catalytic converters with a single aftermarket unit is technically NOT legal, this approach may suit your emissions needs. We suggest you contact your local emissions testing facility for more information. Gaskets sold separately.

    Racing Beat Muffler (Pair) +”Y” Pipe, 86-92 All

    1986-92 RX-7 Street Exhaust System
    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!

    The 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. Racing Beat 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.

    EXHAUST PRE-SILENCER WITH DOWN PIPE, 88 CONVERTIBLE MANUAL

    Racing Beat Exhaust Pre-Silencer with Down Pipe, 88 Convertible Manual Transmission Non-Turbo

    Down Pipe with Presilencer – 1988 RX-7 Convertible Non-Turbo (w/Manual Transmission) – The 1986-92 13B 6-port engines, in stock form with the factory fuel injection, produces similar power gains with either our Header/Presilencer combo or our RX-7 Down Pipe/Presilencer combination. If you have no intentions of installing RB’s Holley intake System (or any other aftermarket carb set-up), we recommend the use of the down pipe/Presilencer combo since it offers a slightly quieter exhaust note, is easier to install and less costly. If you are intending to upgrade the intake or fuel injection system, the Header/Presilencer combo offers the greatest performance potential.

    The 1988 RX-7 Convertible (w/ Manual Transmission) Down Pipe/Presilencer combination incorporates a 2.5-inch O.D. Down Pipe and our perforated stainless steel core and stainless steel wool-packed Presilencer to boost power approximately 13% – an 18 horsepower increase on a 1987 RX 7- and maintain a comfortable exhaust noise level during full power driving.

    The replacement pipe connects to the factory exhaust manifold, and the presilencer connects to the factory Y-pipe, replacing all catalytic converters and intermediate tubing. (The downpipe cannot be used as a “bolt-up” component to replace just the catalytic converters.)

    The Racing Beat presilencer is equipped with an exhaust back-pressure tube for correct operation of the 6-port actuators. Installation of this requires the removal of the air control and check valve and the air pump. This kit includes all necessary mounting hardware, air control & check valve cover plate, and gaskets (1 Back Pressure Pick-up and 3 Replacement Pipe-to-Presilencer gaskets).
