Enhancements to the factory-installed exhaust system of the Saturn Sky roadster represent a modification undertaken to alter its performance characteristics, sound profile, or aesthetic appeal. These modifications typically involve replacing components like the mufflers, resonators, or exhaust piping with aftermarket parts designed for improved flow or a different tonal quality. For instance, a system employing larger diameter piping and a high-flow muffler might be installed to reduce backpressure.
The impetus for modifying this component stems from several factors. Performance enthusiasts often seek to increase horsepower and torque by reducing exhaust restriction. Others are drawn to the desire for a more aggressive or refined exhaust note. Furthermore, some upgrades offer visual improvements through the addition of polished exhaust tips or aesthetically enhanced mufflers. Historically, the automotive aftermarket has provided a wide array of options tailored to various performance and sound preferences, catering to the specific needs of Sky owners.
