DL: Background-In the subject vehicles the front catalytic converter internal components may become deteriorated and begin to
rattle. If continually operated in this condition, the deteriorated components could become dislodged and restrict
the exhaust flow. If this occurs, the vehicle may illuminate a check engine light, and, depending on the level of
exhaust restriction, the vehicle may experience a reduction in power.
Toyota has developed a new exhaust pipe with catalytic converters to prevent this condition from occurring.
