Complete Dual Exhaust System
The key to obtaining power from the rotary engine is first and foremost in the exhaust. Any changes to the intake and/or engine ports will not reach their full potential if the exhaust is not done first, or at the same time. If you are on a budget, or need to do improvements in stages, the exhaust MUST be done first whenever possible. Racing Beat offers a true dual exhaust for all models of 1986-92 non-turbo RX-7s. This complete bolt-on system utilizes all of the stock hangers and hanger positions.

Complete Single Exhaust System
The Racing Beat single exhaust system consists of a header, presilencer, Y pipe, and mufflers. The system produces good power over stock, although not quite as much as the dual system. This system fits all 86-92 non-turbo models.

On the 1986-88 13B 6-Port engines, the auxiliary intake actuators are operated by backpressure from the exhaust system. On the later 1989-92 13B 6-Port engines, these actuators are operates by air pressure from the emissions control air pump. Installation of this header does NOT require the removal of the air pump, and therefore the performance of the 6-port actuators is not affected.
