RX7 Exhaust

One of the most popular ways to modify the Mazda RX7 is to change out the factory RX7 exhaust system.
A cat back exhaust is one of the most common modifications for many RX7 enthusiasts. A cat back RX7 exhaust consists of a muffler or a pair of mufflers, and a pipe that runs the exhaust from the catalytic converter to the back of the car.
The goal of an aftermarket exhaust system is to reduce the amount of backpressure and restriction in the exhaust. When the gas flows freely out the tailpipe, the engine has to work less hard to push the air out and more power is freed up to drive the wheels. Many owners also want to install an aftermarket exhaust so they can personalize the look and sound of their cars.
It should be noted that the RX7, as it is powered by a rotary and not a traditional piston engine, will not sound like most cars. So before buying an aftermarket exhaust, an owner should listen to the clips below in order to know what to expect from an RX7 exhaust sound.
