“Why is my Muffler so loud?”

Do people hear your vehicle coming down the street before they can actually see it? This can be an embarrassing situation. A muffler that is suddenly noisy is often caused by the driver hitting something while on the road, damaging the exhaust system. Rust can also be a culprit of holes in the muffler, resulting in a noisy muffler which gets progressively worse as the holes get bigger.

Exhaust systems in newer vehicles may now last well over 100,000 miles without causing any concerns. But because the exhaust system is exposed to the conditions of the road, damage may occur without warning. The parts of the exhaust system that can be damaged include:


  • Manifold
  • Pre-catalytic converter
  • Front pipe
  • Catalytic converter
  • Intermediate exhaust pipe
  • Front muffler
  • Rear exhaust pipe
  • Rear Muffler

If you do hear a loud noise and you suspect it is the exhaust system, be sure to keep fresh air coming into the vehicle and don’t sit in the car while it’s idling. If there is a leak, carbon monoxide, a toxic gas, can get into the interior of the car. There is no distinguishing odor so it is easy to be overcome by it.

In order for your vehicle to keep running smoothly, all of its components need to be in good working order. Taking the time for regular car inspections and keeping up with needed repairs is the best way to ensure that everything is working as it should. This inspection should include the exhaust system.
