In layman’s terms, a catback exhaust system provides a smoother, more streamlined path for exhaust gases to exit your car, allowing your engine to work more efficiently. When catalytic converters were first introduced, most vehicles used carburetors that provided a relatively rich air-fuel ratio. Oxygen (O2) levels in the exhaust stream were therefore generally insufficient for the catalytic reaction to occur efficiently.
