High Mile Automotive Muffler Repair Services

Your exhaust system is not only tasked with reducing engine noise, but it also is responsible for reducing harmful emissions from entering the atmosphere. Broken or leaky exhaust parts can compromise your vehicle’s engine performance, increase emissions, and even let toxic gasses into your cabin, undetected.

High Mile Automotive 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. 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.

What is the difference between a muffler and an 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 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 down-pipe 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.
