EXHAUST HEADER 12A, 79-80 RX7
Racing Beat 12A Exhaust Header, 79-80 RX7
| SKU: | 16008 |
EXHAUST HEADER 12A, 79-80 RX7
The Racing Beat RX-7 Header with Heat Exchanger Outlet Flange is intended only for use on the 1979-1980 RX-7. This header will bolt-up directly to the stock heat exchanger unit, or the Racing Beat Mini-Presilencer unit. While replacing the stock heat exchanger does not offer any significant horsepower increase, for racing applications 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.
