Exhaust System - Catalytic Converter Noise


SOURCE: Honda Service News

TITLE: Catalytic Converter Noise? Check the Heat Shield

APPLIES TO: All models

SERVICE TIP:

Got a vehicle in your shop that buzzes or rattles, and you suspect the catalytic converter is the culprit? Before you start replacing the converter, first check the heat shield area. If there any stones or debris trapped inside, they can cause buzzing or rattling.
