A catalytic converter is a type of exhaust system that uses catalyst to reduce emissions. Catalytic converters are often used in high-performance vehicles, such as sports cars and racecars. A turbocharged exhaust also uses turbochargers to increase power and performance. Turbocharged Exhaust systems are becoming increasingly popular because they provide more power while reducing emissions. They can be found on luxury cars, such as Ferraris and Lamborghinis, as well as fuel-efficient cars, like the Honda Civic and Toyota Camry.
