Exhaust Pipe: Service and Repair

REMOVAL PROCEDURE

NOTICE: Do not over-flex or damage the flex decoupler joint when moving the flex decoupler joint from the normal mounting position. The flex decoupler joint will flex a maximum of six degrees which is equivalent to the pipes connected at the joint which move 1 inch for each foot length of pipe. A three foot pipe would move a maximum of three inches.
