In the early days of the automobile, exhaust systems were simple pipes allowing the byproducts of combustion to flow away from the occupants of the vehicle. They were loud, smelly, and dirty. Mufflers, using a similar design as pistol silencers, were developed to reduce the volume of the engine.

Later on, environmental research discovered the cost of the petroleum emissions, and forced the development of filters to drastically reduce the amount of pollution cars put into the air. Besides a well-tuned engine, the most important reduction of pollutants comes from the Nissan 200SX’s catalytic converter.

At the cost of a few horsepower, the catalytic converter, or “cat,” cuts the damaging CO2 emissions by a large margin. As technology has advanced, cats have become more efficient by allowing better airflow through the system. The heat and particles that flow through the catalytic converter means that they tend to wear out. Eventually, rust will eat its way into the exhaust system, and the components need to be replaced. Fortunately, whenever you have to change your exhaust parts, you can upgrade for a relatively small amount of money over the OEM parts, giving you more horsepower and a cleaner burn. There are a variety of manufacturers out there for the Nissan 200SX catalytic converter and other exhaust components, offering different design philosophies. You can tune the exhaust note, change the overall look of the exhaust system, or gain horsepower. If you notice rust beginning to show on your catalytic converter, it is time to replace it, especially if you live in a state with emissions inspection. You can order a new Nissan 200SX catalytic converter or an entire new exhaust system from our convenient online catalogue.We have an exhaust to fit every need and budget.
