EXHAUST PRE-SILENCER WITH DOWN PIPE, 89-92 CONVERTIBLE AUTOMATIC TRANSMISSION
Racing Beat Exhaust Pre-Silencer with Down Pipe, 89-92 Non-Turbo Automatic Transmission Convertible
Down Pipe with Presilencer – 1989-92 RX-7 Convertible Non-Turbo (equipped w/Auto 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 RX-7 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 1989-92 RX-7 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. It is not possible to use just the down pipe to replace only the catalytic converters. The use of the presilencer is required to complete the connection to the y-pipe. Although a short length of tubing can be substituted in place of the presilencer, we do not offer (or suggest) this due the unacceptable increase in exhaust noise.
The down pipe is equipped with a mounting flange for the oxygen sensor. This kit includes all necessary mounting hardware, air control & check valve cover plate, and gaskets (3 Replacement Pipe-to-Presilencer gaskets).

EXHAUST “Y” PIPE-RACING BEAT, 86-92
Racing Beat Exhaust “Y” Pipe, 86-92
The Racing Beat Y-pipe for the 1986-92 RX-7 (All Models) is a perfect replacement for a failing stock component. The Racing Beat Y-pipe is slightly larger in diameter than the stock non-turbo Y-pipe, and matches the diameter (2.5″ OD) of the stock TURBO II Y-pipe. Therefore, if you are replacing the muffler(s) on a TURBO II application, and unless the original stock Y-pipe is failing, there is no performance benefit to be gained from the addition of this Y-pipe. This Y-pipe includes the Cat-to-Y-pipe gasket. If needed, the Y-pipe outlet gaskets can be purchased separately. Manufactured by Racing Beat using heavy-walled steel tubing and laser cut flanges then finished with a chrome-plated surface coating for excellent durability.
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.SKU: 16447 -
