WARNING: This page is about a different car, the 2002 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: 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.

Important:  A service muffler will be needed when replacing the intermediate pipe on an originally equipped, welded system.

  1. Raise the vehicle. Refer to LIFTING AND JACKING THE VEHICLE in General Information.
