Racing Beat offers our complete Road Race RX-7 Exhaust System for the 1986-88 RX-7. This complete RX-7 exhaust system is intended for use on RX-7 applications running under the extremes of road racing, drag racing, or any high performance, high RPM application. This dual exhaust system has been designed to maximize the exhaust gas scavenging benefits while maintaining reasonable sound level outputs.
NOTE: This exhaust system will not work on automatic transmission equipped vehicles.
The following is included in this RX-7 exhaust system:
1986-88 RX-7 Road Race Header
The Racing Beat Road Race Header for the 1986-88 13B engine features thick-walled construction for excellent durability and sound level reduction. Also included on this header is a critical exhaust back-pressure pickup tube which assures the correct operation of the 6-port intake actuators mounted on the engine. (If you have removed these intake actuators or have rendered them inoperable, you can install the 1989-92 Road Race system instead.)
Road Race Presilencer
Mating to the outlet of the header is the Racing Beat Road Race Presilencer. The straight-through dual presilencer unit offers beneficial sound reducing qualities by trapping a significant level of the harsh rotary exhaust note.
Road Race Y-Pipe
The Racing Beat Y-Pipe section routes the exhaust gases exiting the presilencer section to each of the Power Pulse muffler units.
Road Race Mufflers (Left and Right Pair)
Sharing the same design technology as our Power Pulse muffler units, the Road Race mufflers (Left and Right) feature all stainless steel construction for superior durability and appearance. Large diameter tubing routes the exhaust gas through each muffler unit, exiting through polished stainless steel tips.
Each Road/Race Exhaust System comes complete with mounting hardware. If needed, replacement rubber hangers can be ordered to replace the original Mazda hanger units.
