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.
Gaskets are not included but are available separately. Two required.
Replacement Rubber Exhaust Hangers
It is our experience that the stock rubber hangers that support the exhaust system can deteriorate and crack with age. We suggest the replacement of these hangers when installing replacement exhaust components. If you require a replacement rubber hanger for use with your Presilencer unit, follow this link for more detailed information.
