As a device that serves to direct gases out of the engine as well as to reduce noise, this exhaust component functions continuously, so it is not uncommon for the muffler to need replacing every five to seven years.

  • Engine Performance: Engine misfires and decreased gas mileage can be caused by leaks.
  • Vibrations: A leak can cause odd vibrations from the gas pedal, steering wheel, or even the entire vehicle.
