When starting a car, the engine noise is often accompanied by sounds from the catalytic converter as it heats up during a cold start. This can lead to a noticeable difference in the vehicle’s sound profile. If you’re looking to eliminate or reduce this noise for a quieter driving experience, there are options available that can help modify the exhaust system or other components to achieve a more pleasant sound. Considering such modifications can enhance your overall driving experience while potentially improving performance as well.
