  • EXHAUST PRE-SILENCER WITH DOWN PIPE, 88 CONVERTIBLE MANUAL

    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).
