Shopping for Muffler

Muffler Shopping Info

How Much Does a Muffler Replacement Cost?

A replacement muffler can cost you anywhere between $50 and $250 on parts alone. An auto repair shop may charge you $80 to $100 for labor, but this may vary depending on your specific vehicle and the rates in your area.

What Is a Muffler?

A muffler is a flask-shaped metal device installed along the exhaust pipe underneath your car. It comes in different designs and sizes but the function remains all the same. It reduces the airborne noise coming from your car’s engine. It suppresses and controls the engine noise by breaking the soundwaves down inside the assembly.

Aside from muffling and improving your vehicle’s performance, mufflers also keep toxic fumes away from the cabin. Some modern mufflers are also known to improve a vehicle’s performance.

Mufflers are highly regulated in different states and modifications are often strictly prohibited. Remember to check your state’s regulations before purchasing an aftermarket muffler.
