Aftermarket exhaust components designed for the Infiniti G37, incorporating resonators and catalytic converter bypass, are engineered to alter the vehicle’s exhaust flow characteristics. These particular devices modify the sound profile of the exhaust system while potentially increasing engine output by reducing backpressure. This type of exhaust modification replaces the factory catalytic converters with straight pipes, and resonators are included to mitigate rasp and drone often associated with catless exhaust systems.
The use of these components can yield improvements in horsepower and torque, particularly in the mid-range and top-end of the engine’s RPM range. Historically, performance enthusiasts have sought such modifications to unlock additional power from their vehicles. However, it is important to note that removing catalytic converters may have implications for emissions compliance, potentially violating local or federal regulations. The presence of resonators aims to refine the exhaust note, creating a more refined and less abrasive sound.
