Racing Beat Dual Exhaust System, 86-88 6 Port Non Turbo Manual Transmission

Racing Beat offers the complete Full Stainless Steel Road Race RX-7 Exhaust System for the 1986-88 RX-7. This completely Stainless Steel 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. The Racing Beat Full Stainless Steel RX-7 dual exhaust system has been designed to maximize the exhaust gas scavenging benefits while maintaining reasonable sound level outputs.

NOTE: This exhaust system is not compatible with automatic transmission equipped-vehicles due to interference issues with the bell housing.

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 6-Port chassis features stainless steel construction for excellent durability. Also incorporated with this header is the requisite exhaust back-pressure pickup tube, necessary to assure 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.

Racing Beat Exhaust System, 86-92 Turbo

1987-91 RX-7 TURBO REV II Complete High Performance Exhaust System – If you own a TURBO II RX-7 and you’ve found your way to this webpage, congratulations! Why? Because your search for an exhaust system for your car ends here. Simply put, this is the ultimate exhaust for any Turbo II RX-7!

The REV TII High Performance RX-7 Exhaust is legendary with FC3S owners.  This RX-7 exhaust system includes a 3-inch OD REV TII Down Pipe from the turbo outlet that mates to a REV TII Presilencer section. The outlet of the presilencer connects to the inlet of the REV TII Y-Pipe which routes the exhaust gases down two 2.375-inch OD (60mm) pipes into a pair of left and right REV TII Power Pulse Mufflers. Once installed, this bolt-on exhaust system increases horsepower approximately 32% – that’s a 59 HP increase on a 1987 Turbo II RX-7!

The REV TII High Performance RX-7 Exhaust system reduces exhaust gas back-pressure significantly, thereby allowing the un-assisted turbo boost pressure to increase to 10-11 psi. (Note: A fuel cut controller device is required to prevent fuel cutoff to the rear rotor above the factory pre-set limit.)

This bolt-on system uses the stock mounting points for ease of installation. Each system is supplied with all necessary mounting hardware and gaskets. (The kit does not include turbo outlet gasket, if needed it can be ordered separately.) The down pipe section is provided with a position for the oxygen sensor.
