The first thing to do in order to find the average cost of replacing an exhaust system is to know the type of exhaust system components needed. Costs range from $25 to $300, depending on the component.
Exhaust components that could need replacing include cat-back exhaust systems, axle-back exhaust systems, exhaust system tips, and high-performance mufflers. After determining the type of system, there are websites that provide estimates, including CostHelper and Exhaust Videos.
Finding the cost of replacing the exhaust system also includes knowing what is included and what is not. Parts and labor should be included; however, the warranty on the muffler may not be very long, and an extended warranty could increase the cost.
