Catalytic Converter: Service and Repair

CAUTION: When a flex decoupler joint is removed from the normal mounting position it is possible to over-flex and damage the joint. Always support the flex decoupler joint and pipe assembly to avoid over-flexing. The flex decoupler joint is designed to flex a maximum of six degrees which is equivalent to the pipes connected to the joint moving no more than 1 inch for every 1 foot length of pipe, (if the pipe connected to the joint is 3 feet long, the end of the pipe could be moved a maximum of 3 inches).
