EXHAUST PRE-SILENCER, 79-80 4-PORT
The Racing Beat Mini Power Pulse Presilencer is designed specifically to replace the Heat Exchanger on 1979-1980 RX-7s to either provide a quieter exhaust with a more pleasant character or because the original Heat Exchanger has failed. This presilencer is 10.625 inches long and 4-inches in outside diameter. The inside diameter, 2 inches, is a straight-through perforated-core design. The end caps are .375-inch thick and fitted with 12mm studs. The inlet end mates to the Heat Exchanger flange at the rear of our header, while the outlet end mates to a catalytic converter flange. Inside, the perforated core is made of stainless steel and is packed with stainless steel wool.
This small presilencer is also ideal for use in the design of a custom exhaust system when space concerns does allow the placement of a longer presilencer. Multiple units can be installed in sequence as need to meet your sound level needs.

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).
