These aftermarket automotive components are designed to replace the catalytic converters in an Infiniti G35. The modification aims to improve exhaust flow. The “resonated” aspect indicates the inclusion of resonators within the pipe structure. These resonators are intended to mitigate some of the increased exhaust noise and drone that typically accompany catalytic converter removal.
Modifying a vehicle’s exhaust system can have several performance-related implications. By reducing backpressure, engine efficiency can potentially improve, leading to increased horsepower and torque. The historical context involves a desire for increased performance gains by enthusiasts, weighed against environmental regulations regarding emissions control. The inclusion of resonators aims to balance performance gains with a more acceptable sound profile, attempting to address a common drawback of deleting catalytic converters.
