SKU: 16405

EXHAUST PRE-SILENCER, 86-88 NON TURBO MANUAL TRANSMISSION

The Racing Beat Power Pulse Presilencer for the 1986-88 RX-7 Non-turbo (w/manual 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.

This same Power Pulse Presilencer is included as a sub-component with the Catalytic Converter Replacement Pipe/Presilencer assemblies we offer for all 1986-88 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 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.

The 1986-92 RX-7 Power Pulse Presilencers are manufactured with a large diameter 2.5-inch I.D. core pipe for improved exhaust gas flow. Additionally, the Power Pulse Presilencers we offer for use with non-turbo 1986-88 6-port engines feature an exhaust gas backpressure sensing tube necessary for proper operation of the 6-port intake actuator valves.

If you are using two Power Pulse Presilencers in conjunction with our Road Racing Header for a long primary system on a 1986-88 13B 6-port engine we recommend using one (1) of our 1984-85 GSL-SE Presilencers equipped with the back pressure sensing tube, and one (1) of our GSL-SE Presilencers standard presilencers used on 4-port engines. With this configuration you will have one presilencer with the backpressure pickup tube, and one presilencer without the tube, which would be suitable for building a long primary center section.

    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.

Both flanges are laser cut from 7/16″ thick steel plate for positive gas sealing. An outlet gasket is included. An engine-to-header gasket is available separately if needed. This header is equipped with an oxygen sensor fitting.
