EXHAUST HEADER 12A, 74-78 DUAL OUTLET
1974-1978 12A Road Racing Header (for non-RX-7 applications) – 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. 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 12A engine) which allows simple swapping between street and race exhaust systems.

The Power Pulse PR-Extreme RX-7 Muffler is compatible with all 1979-85 RX-7 muffler rear mounting positions and retains the factory stock appearance; this PR-Extreme RX-7 Muffler includes an inlet of 3″.
The Racing Beat Universal Power Pulse PR-Extreme RX-7 Muffler is manufactured by the same exhaust components manufacturer that has produced the “tried and proven” First Generation RX-7 Power Pulse mufflers (1979-80, 1981-82, and 1984-85) since the mid-1980s. Utilizing a heavy-walled canister shell and extremely durable heat and noise insulating materials, the Racing Beat Power Pulse PR-Extreme RX-7 Muffler is engineered for the high exhaust gas temperatures found in rotary engine applications.
The main body of the muffler canister measures 8 inches in diameter and 18 inches in length. The dual outlet tips are completely chrome-plated with straight-cut outlet.
Now may be the time to consider replacing the old rubber muffler hangers on your RX-7. New replacement hangers will ensure correct alignment of the RX-7 muffler canister and tip position in the bumper opening.
