These aftermarket automotive components modify the exhaust system of a specific Infiniti model to enhance performance and alter the sound profile. They replace the catalytic converters, which are emission control devices, with straight-through pipes containing resonators. Resonators help to mitigate the harsh or raspy sounds often associated with removing catalytic converters. For example, installing these parts can result in a louder, more aggressive exhaust note and potentially improved horsepower output.
The appeal of these components lies in the potential for increased engine power and a more desirable exhaust tone. Eliminating catalytic converters reduces backpressure, allowing exhaust gases to flow more freely, which can result in performance gains. The resonators mitigate unwanted noise frequencies, producing a more refined sound. Historically, modifications to exhaust systems, including the replacement of catalytic converters, have been a common practice among automotive enthusiasts seeking improved performance, though such modifications can impact emissions compliance.
