How Much Does An Exhaust System Cost?
The price of aftermarket exhausts varies depending on the type of your car and the quality of the system. Clearly, header-back exhausts are the most expensive and range from $800 to over $2000.

Does Aftermarket Exhausts Add Horsepower?
By making your engine breathe better, performance exhausts can extract more power at certain RPMs. However, not all engines gain that much power. Smaller four-cylinder engines will gain much more power than large-displacement V8 engines.
The more powerful the engine is, the less work it has to do to beat the restrictions of the exhaust. Also, cars that are already performance-tuned from the factory might not see improvements in power whatsoever.
Do Aftermarket Exhausts Improve Fuel Economy?
As expected, as much as a performance exhaust system improves power, it can also improve fuel economy. This is because performance exhausts enhance the air-flow of exhaust gases, which makes engines more efficient.
The highest-quality aftermarket exhaust system can improve the fuel economy by up to 5%, which is a pretty amazing result. Nonetheless, some cheap and low-quality exhausts may hurt fuel consumption.
