The cost to repair or replace an automobile's muffler and exhaust system can range from $75 to $2,500, as of May 2015. Many factors affect the total price of the repair or replacement of a muffler and exhaust system.
The make, model and year of vehicle, type of muffler required, where the muffler is purchased and labor costs are all key elements that affect total cost. The extent of work required also affects the price. If the exhaust pipes and catalytic converter need to be replaced along with the muffler, the bill will be substantially higher. It's important to research service stations first and get written estimates of the costs before getting any work done on a vehicle.
