These aftermarket automotive components replace the factory catalytic converters found on the Nissan 370Z. Characterized by their “resonated” design, they incorporate a small chamber or resonator within the pipe to mitigate some of the harsh exhaust frequencies that can result from removing the catalytic converters. This design aims to strike a balance between increased exhaust flow and a more refined exhaust note. As an example, installing them allows for quicker evacuation of exhaust gases from the engine.
The core function of these parts lies in their potential to enhance engine performance by reducing backpressure in the exhaust system. Decreasing backpressure can, in turn, lead to increased horsepower and torque. Moreover, some enthusiasts opt for these to alter the exhaust sound profile of their vehicle, often aiming for a louder or more aggressive tone. Historically, modifications to exhaust systems have been a common method for improving engine output, particularly in performance-oriented vehicles.
