Catalyst Shield: Service and Repair

NOTE: At idle or during normal driving conditions, a buzz or rattle may be detected, which can be traced to the exhaust system. The heat shield attachment to the muffler or catalyst may come free. The loose shield will vibrate off the muffler or three way catalytic converter and cause the buzz or rattle.

NOTE: The three way catalytic converter may have two cans. If shields on both cans are loose, four clamps (two for each) will be required.
