  • Unusual smell from exhaust
  • Rattle type noise from under the vehicle
  • Vehicle may fail an emissions test

Resonator Related Repair Advice

  • Failure of the exhaust system may cause exhaust gases to enter the passenger compartment. The exhaust gases contain carbon monoxide (CO), which can cause drowsiness and death.
  • The exhaust hangers and mounts should be inspected whenever an exhaust system component is replaced
