Muffler and Exhaust Service

Request Appointment

A loud muffler and a dragging tailpipe may be classic comedy gold, but a damaged exhaust system is no joke. Broken or leaky exhaust parts can compromise your vehicle’s engine performance, increase emissions, and even let toxic gasses into your cabin, undetected.

Midas services all parts of your vehicle’s exhaust system:

  • Exhaust valve and piston: Engine parts that force exhaust fumes out from the combustion chamber (where they are created) to the exhaust manifold.
  • Exhaust manifold: The path from the piston to the catalytic converter. In or near this area, there will be one or more oxygen sensors.
  • Catalytic converter: Converts some toxins to carbon dioxide (CO2) and water for cleaner emissions -- though the exhaust is still poisonous in confined spaces (and CO2 is a greenhouse gas). More oxygen sensors may be located after the catalytic converter to help monitor its performance.
  • Exhaust pipe: Carries the cleaner exhaust gasses to the muffler.
  • Muffler: Reduces the noise of combustion and expulsion of exhaust.
  • Tailpipe: Where exhaust leaves your vehicle.

Muffler Replacement and Repair with North America’s Leader

What is the difference between a muffler and the exhaust?

A muffler is one component of a vehicle’s exhaust system. Its job is to reduce the noises of engine combustion and evacuation of exhaust gasses. The entire exhaust system starts with your engine’s exhaust valve and exhaust manifold and continues through a series of pipes to at least one catalytic converter, muffler, and tailpipe.

Dual exhaust systems may employ one or two catalytic converters and mufflers, depending on the configuration. Single exhaust systems are far more common and employ a single catalytic converter and muffler, occasionally featuring two tailpipes.

How much does it cost to fix a muffler?

Muffler repair prices vary widely, depending on the complexity of the repair and the amount of labor involved. Based on U.S. pricing trends before discounts, it can cost from $30-$50 to at least $500 to fix a muffler. The most common muffler repairs are patching holes, tightening a loose connection, and re-welding a dangling muffler back in place. If your muffler itself is damaged, replacement may be more cost-effective than repair.

Find your local Midas and request an appointment today. Our Midas Auto Service Experts® take the time to thoroughly explain your muffler’s condition and discuss the best muffler repair vs. replacement options for your budget. We provide a written estimate before working on your vehicle.

How much does it cost to replace a muffler?

Based on U.S. pricing trends before discounts, it costs $200-$600 to replace a muffler, depending on your vehicle and location. The first $100 or so covers labor, but new muffler prices vary considerably from vehicle to vehicle. The wide range of parts pricing explains the wide range of overall muffler replacement costs.

How long does it take to replace a muffler?

The simplest muffler replacement takes 30-60 minutes depending on your vehicle. Allow another hour or two if the mid-pipe or downpipe also needs service. These pipes can be difficult to reach, and may need to be replaced along with your muffler.

What are the signs of a bad muffler?

Here are some signs that your muffler needs service:

  • Louder exhaust sounds
  • Clunking from the muffler
  • Engine rattling or misfiring
  • Dangling or dragging tailpipe
  • Condensation from the exhaust pipe
  • An unusual exhaust smell

How long does a muffler last?

The lifespan of a muffler is traditionally estimated at 40,000-80,000 miles. But your muffler may fail sooner under harsh driving conditions like cold weather, corrosive road salt, and damage from road debris and potholes. You can help mitigate corrosion by frequently having your vehicle’s undercarriage washed, and choosing a replacement muffler made of corrosion-resistant steel when the time comes.

Can I drive a car with a broken muffler?

A car with a broken muffler may or may not be safe to drive. Muffler damage often goes hand in hand with an Exhaust Leak – a serious safety hazard. Carbon monoxide in your cabin can affect your driving ability and cause health problems before you realize it’s there. Any problem with your exhaust system should be evaluated by a qualified mechanic.
