Exhaust System

Racing Beat's Road Race Header is the first step in building a serious racing exhaust system. The engine-to-pipe flange is laser cut from 7/16" thick flat steel. Like all of the headers we manufacture, the Road Racing Header is constructed with 2" OD mild steel tubing, .125" wall thickness, and mandrel-bent tubing throughout.

Outlet flange gaskets, bolts, and nuts are included. An engine-to-header gasket is not included, but is available separately. An Air Control and Check Valve Cover Plate (1979-80 or 1981-92) is required when using this header with a stock intake system. The Road Race Header can also be used as the basis for a custom streetable exhaust system in any car from 1971-92 which allows simple swapping between street and race exhaust systems.

These headers can used as a bolt-on component with the Street Port Center Section Pipe (1979-85 12A & 13B - except GSL-SE) or (1984-85 GSL-SE) that we offer for these model years.

Fits 6 port 13B engines (Non Turbo) Racing Beat

Racing Beat's Road Racing Header for the 1984-91 RX-7 13B (6-Port) is the first step in building a serious racing exhaust system. The engine-to-pipe flange is laser cut from 1/5" thick flat steel. Like all of the headers we manufacture, the Road Racing Header is constructed with 2" OD mild steel tubing, .120" inch wall thickness, and mandrel-bent tubing throughout.

Outlet flange gaskets, bolts, and nuts are included. If needed, an engine-to-header gasket is available separately. An Air Control and Check Valve Cover Plate is required when using this header with a stock intake system. The Road Race Header can also be used as the basis for a custom streetable exhaust system in any car from 1971-92 (equipped with a 6-port engine), which allows simple swapping between street and race exhaust systems.

This header can used with the Street Port Center-Section Pipe 1979-85 12A & 13B except GSL-SE or 1984-85 GSL-SE.

Racing Beat offers a full 304-stainless steel catalytic converter replacement pipe for RX-8 racing applications. The weight of this pipe is 10 lbs.

This mandrel-bent 3" OD racing pipe is a direct bolt-on replacement for the stock catalytic converter section.

This pipe utilizes a genuine OEM rear mounting flange for a secure fit to the stock (or an aftermarket) exhaust system. The race pipe is equipped with a sensor fitting for the oxygen sensor. (Note: Placement of the sensor in the pipe will cause the "check engine" light to be illuminated, but performance and engine systems will not be affected.) Removal of the OE catalytic converter/presilencer section will result in a noticeably louder exhaust tone.

The Racing Beat Streetable RX-7 Header with Heat Exchanger Flange Outlet is intended only for use on the 1979-1980 RX-7. It is available in both 12A and 13B versions to accommodate those who install the 13B engine in the 12A equipped RX-7 chassis.

While replacing the stock Heat Exchanger does not offer any significant horsepower increase, we recommend replacing the Heat Exchanger with our Mini Power Pulse Presilencer to reduce exhaust noise. Engine-to-pipe and heat exchanger gaskets are not included, but are available separately or as part of a complete exhaust system.

This Streetable Header/Collector is designed for a bolt-on installation, when used with the appropriate Power Pulse Presilencer in all 1981-83 RX-7s. The combination of this Header/Collector and the appropriate presilencer replaces the stock exhaust manifold and all catalytic converters, along with any intermediate pieces of tubing.

The Header/Collector assembly is constructed with .125-inch wall, mandrel-bend, mild steel tubing for increased durability. Both flanges are flame-cut from .4375-inch thick steel plate for positive gas sealing. An outlet gasket is included. An engine-to-header gasket is available separately.

This RX-7 Header is designed for a bolt-on installation, when used with the appropriate Power Pulse Presilencer in all 1981-85 RX-7 with 13B conversion or the 1984-85 RX-7 GSL-SE models. The combination of this RX-7 header and the appropriate presilencer replaces the stock exhaust manifold and all catalytic converters for use in racing applications, along with any intermediate pieces of tubing. This header includes a mounting flange for the oxygen sensor.

The Racing Beat RX-7 header assembly is constructed with .120-inch wall, mandrel-bend, mild steel tubing for increased durability and sound suppression. Both flanges are laser-cut from .5-inch thick steel plate for positive gas sealing. An outlet gasket is included. An engine-to-header gasket is available separately if needed.

This header has the 6-port actuator pick-up tube & oxygen sensor position for use on a 1986-88 RX-7 13B.

Road Race Header (w/ 6-port actuator pick-up tube & oxygen sensor position for use on a 1986-88 RX-7 13B) - This model Road Race Header that we offer is intended to bolt-up to the Road Race Presilencer section. Please note: that this header is not compatible with the Street Port Center Section that we offer for the earlier 1984-85 RX-7 GSL-SE - only with the Road Race Presilencer section referenced above. This header is not compatible with the 1988-91 RX-7 convertible chassis equipped with the automatic transmission: the header outlet will make contact with the transmission case.

Racing Beat's Road Racing Header is the first step in building a serious racing exhaust system. The engine-to-pipe flange is laser cut from 7/16" thick flat steel for superb exhaust gas sealing qualities. Like all of the headers we manufacture, the Road Racing Header is constructed with 2" OD mild steel tubing, .120" wall thickness, and mandrel-bent tubing throughout. This header weighs approximately 15.5 lbs and is approximately 28" in length.

On the 1986-88 13B 6-Port engines, the auxiliary intake actuators are operated by back pressure from the exhaust system. This header features a back pressure pick-up tube that allows for the correct operation of the 6-port intake actuators. Also included on the header is an oxygen sensor position for cars that require an oxygen sensor for correct operation.

Outlet flange gaskets, bolts, nuts, AC & CV cover plate, and installation instructions are included. An Engine-to-Header Gasket is not included, but is available separately if needed.

1974-1978 13B Road Racing Header is ideal for RX-2, RX-3, RX-4, Repu, and COSMO - Racing Beat's Road Racing Header is the first step in building a serious racing exhaust system. The engine-to-pipe flange is flame cut from .4375-inch thick flat steel. Like all of the headers we manufacture, the Road Racing Header is constructed with 2-inch O.D. mild steel tubing, .125-inch inch wall thickness, and mandrel-bends throughout.

Outlet flange gaskets, bolts, and nuts are included. Engine-to-pipe gaskets are not included, but are available separately.

The Road Race Header can also be used as the basis for a custom streetable exhaust system in any car from 1971-92 which allows simple swapping between street and race exhaust systems.

Doesn't fit Repu. The Street-able Header/Collector (less outlet flange) is ideal for RX-2, RX-3, RX-4, and COSMO (does not fit rotary pickup) custom exhaust installations. The flame-cut, .4375-inch thick engine flange provides positive sealing and alignment. By integrating the collector with the header we reduce the effort and cost in completing the exhaust system. Engine-to-pipe gaskets are not included but are available separately. An Air Control and Check Valve Cover Plate is required when using this header with a stock intake system.

If the stock resonator is eliminated during installation of this unit, we strongly recommend selecting a Power Pulse Presilencer and installing it in place of the resonator to maintain a pleasant noise level and character.
