Exhaust cutouts are performance parts that allow you to control the flow of exhaust gases in your vehicle's exhaust system. When engaged, they create a louder, more aggressive exhaust sound and can potentially improve horsepower by reducing backpressure. Exhaust cutouts are available in electric or manual versions. Electric cutouts offer the convenience of opening and closing the valve with a switch, while manual cutouts require a cable or lever to operate. Choosing an exhaust cutout depends on your desired functionality and budget.
