Symptoms of Wear or Failure

  • Louder than normal engine noise from the exhaust system
  • Unusual smell from exhaust
  • Rattle type noise from under the vehicle
  • Vehicle may fail an emissions test

  • The exhaust hangers and mounts should be inspected whenever an exhaust system component is replaced
